Create and set clientAttribute to ADF Faces component programmatically to pass value on client side JavaScript

This post is next in series of "Working with ADF Faces Components programmatically"

So this post is about creating client Attribute, applying it to component and setting it's value programmatically
this requirement comes in picture when user is dealing with dynamic layout means components are created programmatically at run time and it is not possible to apply clientAttribute and other properties declarative

In this i am extending my previous post -
Apply Client/Server listener to programmatically created components, apply JavaScript to ADF Faces components at run time

In previous post i have described about applying client listener and server listener programmatically
here we will see how to pass a variable value to java script function using client attribute
You can read more about af:clientAttribute here

From oracle docs-
The clientAttribute tag specifies the name/value for an attribute which will both be made available both on the server-side (Faces) component as well on on the client-side equivalent. This tag will be ignored for any server-rendered components, as it is only supported for the rich client. ClientAttributes are not synchronized to the server since unknown attributes from the client are not synchronized to the server.



Lets' see how we can do this ,It's simple just check this code -

//Code from previous post to create inputText programmatically 
//http://www.awasthiashish.com/2015/05/apply-clientserver-listener-to.html
        RichInputText ui = new RichInputText();
        ui.setValue("Programmatically Created Input Text");
        ui.setId("pit1");
        ui.setContentStyle("width:200px;color:navy");

Here i am not writing code to apply client/server listener again , refer previous post for that
See the code to add client attributes to component (inputText)

        // A Set that contains all clientAttributes
        java.util.Set<String> clientAttributes = new HashSet<String>();

        // Add client attribute's name
        clientAttributes.add("clientAttribute1");
        clientAttributes.add("clientAttribute2");
        clientAttributes.add("clientAttribute3");

        //Add these attributes to a UI Compoenent
        ui.setClientAttributes(clientAttributes);

        //here assign values to client attributes
        ui.getAttributes().put("clientAttribute1", "Oracle ADF");
        ui.getAttributes().put("clientAttribute2", 9999);
        ui.getAttributes().put("clientAttribute3", "Ashish Awasthi");

So all done , now check it
For that i have used this javascript method

function demoJsFunction(evt) {
                  var comp = evt.getSource();
                  alert(comp.getProperty('clientAttribute1'));
                  alert(comp.getProperty('clientAttribute2'));
                  alert(comp.getProperty('clientAttribute3'));
               
                  evt.cancel();
              }

this method is called using client listener on input text and see the alert messages
First client attribute value-

Second client attribute value-

Third client attribute value-

So this is working :)

Apply Client/Server listener to programmatically created components, apply JavaScript to ADF Faces components at run time

Hello All

This post is next in series of "Working with ADF Faces Components programmatically"
Previous posts are-

Creating dynamic layout (form and UI Component) using ADF Faces
Get Value from programmatically created components , Iterate over parent component to get child values in ADF Faces 
Apply ActionListener to programmatically created buttons/link in ADF

Now this post is about applying client listener & server listener (to execute some javascript function) to a programmatically created component (inputText, outputText etc)

Let's see the implementation part (Jdev 12.13) -

• First created a FusionWebApplication and a page in viewController project
• Dropped a button on page , on this button action i will create an inputText programmatically
• To create new inputText i have added following code (described in previous posts)





    /**Method to add dynamically created component to a parent layout
     * @param parentUIComponent
     * @param childUIComponent
     */
    public void addComponent(UIComponent parentUIComponent, UIComponent childUIComponent) {
        parentUIComponent.getChildren().add(childUIComponent);
        AdfFacesContext.getCurrentInstance().addPartialTarget(parentUIComponent);
    }





        //Code to create af:inputText and add it to panelgroup layout
        RichInputText ui = new RichInputText();
        ui.setValue("Programmatically Created Input Text");
        ui.setId("pit1");
        ui.setContentStyle("width:200px;color:navy");
        //getParentGroupLayoutBind is the component binding of parent panel group layout
        addComponent(getParentGroupLayoutBind(), ui);



• Now first part is done - Creation of input text , next is to assign client and server listener to it
  So for that first we have to add some JavaScript function in page that will be called using clientListener
  I have added this JavaScript function in page, it just fires a custom event from client and pass component value as parameter



        function demoJsFunction(evt){
          var comp = evt.getSource();
          alert(comp);
          AdfCustomEvent.queue(comp, "ServerEventToGetValue", {fvalue:comp.getSubmittedValue()}, true);
          evt.cancel();
        }
      



• One more thing is to define server listener method in managed bean so that we can apply it to inputText at run time



    /**Server Listener - It will be called on execution of client side javascript
     * @param clientEvent
     */
    public void testServerListener(ClientEvent clientEvent) {
        //To get value passed from Client Event
        String val = clientEvent.getParameters().get("fvalue").toString();
        FacesMessage msg=new FacesMessage("Server Listener Called and value in inputText is - " + val);
        msg.setSeverity(FacesMessage.SEVERITY_INFO);
        FacesContext.getCurrentInstance().addMessage(null, msg);
       
    }



• Now create clientListener/ServerListener programmatically and assign both to inputText
  Pass server listener method name along with managed bean name



        // Create new Client Listener and assign method name and type
        ClientListenerSet CL = new ClientListenerSet();
        CL.addListener("click", "demoJsFunction");
        //Add Server listener , assign client event name and resolve pre-defined serverlistener
        CL.addCustomServerListener("ServerEventToGetValue",
                                   getMethodExpression("#{viewScope.Testbean.testServerListener}"));

        // Add clientListener/ServeListener to inputText
        ui.setClientComponent(true);
        ui.setClientListeners(CL);


Helper method to resolve expression-

    /**To Resolve ServerListener method
     * @param s
     * @return
     */
    public MethodExpression getMethodExpression(String s) {

        FacesContext fc = FacesContext.getCurrentInstance();
        ELContext elctx = fc.getELContext();
        ExpressionFactory elFactory = fc.getApplication().getExpressionFactory();
        MethodExpression methodExpr = elFactory.createMethodExpression(elctx, s, null, new Class[] {
                                                                       ClientEvent.class });
        return methodExpr;

    }



• All done , now run application and check , click on button it will create a inputText

         now click on input text and see server listener is called :)

This is how we can apply javascript in programmatic created components

Apply ActionListener to programmatically created buttons/link in ADF

This post is next in series of "Working with ADF Faces Components programmatically"
Previous posts are-
Creating dynamic layout (form and UI Component) using ADF Faces
Get Value from programmatically created components , Iterate over parent component to get child values in ADF Faces

Now this post is about applying ActionListener to a programmatically created button or link
Let's start (Jdev 12.13) -

• First created a FusionWebApplication and a page in viewController project
• Dropped a button on page , on this button action i will create a link programmatically and assign actionListener to it
• To create new link i have added following code (described in previous posts)





    /**Method to add dynamically created component to a parent layout
     * @param parentUIComponent
     * @param childUIComponent
     */
    public void addComponent(UIComponent parentUIComponent, UIComponent childUIComponent) {
        parentUIComponent.getChildren().add(childUIComponent);
        AdfFacesContext.getCurrentInstance().addPartialTarget(parentUIComponent);
    }




       //Creating Link programmatically on button click     
        RichLink ui = new RichLink();
        ui.setId("li1");
        ui.setText("Programmatically Created Link");
        ui.setInlineStyle("font-weight:bold;");
        //Add this link to parent form layout
 //ParentGroupLayoutBind is the component binding of panelGroupLayout
        addComponent(getParentGroupLayoutBind(), ui);



• After this we are able to create a new Link on click of button, now next is to assign ActionListener to this Link
  For this first i have to define an ActionListener method in bean. So i have added this 



    /**Action Listener to be applied on dynamically created button
     * @param actionEvent
     */
    public void actionForProgLink(ActionEvent actionEvent) {
        FacesMessage infoMsg = new FacesMessage("Action Listener Invoked");
        infoMsg.setSeverity(FacesMessage.SEVERITY_INFO);
        FacesContext.getCurrentInstance().addMessage(null, infoMsg);
    }



• Now how to assign this ActionListener to that dynamically created Link?
  See the Code-



    /**Method to to resolve actionListener
     * @param actionName
     */
    private ActionListener getActionListener(String actionName) {
        //here Testbean is the name of ManagedBean
        MethodExpression methodExp = getMethodExpressionForAction("#{viewScope.Testbean." + actionName + "}");
        return new MethodExpressionActionListener(methodExp);
    }


Helper method to resolve ActionListener-

    private MethodExpression getMethodExpressionForAction(String actionName) {
        Class[] argtypes = new Class[1];
        argtypes[0] = ActionEvent.class;

        FacesContext facesCtx = FacesContext.getCurrentInstance();
        Application app = facesCtx.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = facesCtx.getELContext();
        return elFactory.createMethodExpression(elContext, actionName, null, argtypes);
    }


Just pass the name of method to resolve it

   //Apply ActionListener on this dynamically created link 

    ui.addActionListener(getActionListener("actionForProgLink")); 

Now time to check , run application :)
First a button appears-

On click of this button a link is created -

Click on this link- programmatically assigned Action Listener is called

Get Value from programmatically created components , Iterate over parent component to get child values in ADF Faces

Sometimes we need to create and add ADF Faces components at runtime , we can do it programmatically
I have posted about this before
Creating dynamic layout (form and UI Component) using ADF Faces

Now this post talks about getting value from programmatically created component, means when user enters value in those component then how to access that value in managed bean

Here i am using Jdev 12.1.3 , Let's see the implementation part

Created a page and added two buttons , one to create component at run time and second one to get values from those components
See page XML source code -

<af:document title="ProgComponent.jspx" id="d1">
            <af:form id="f1">
                <af:spacer width="10" height="10" id="s3"/>
                <af:button text="Create Components " id="b1"
                           actionListener="#{viewScope.GetValueProgCompBean.createComponentsAction}"/>
                <af:spacer width="10" height="10" id="s1"/>
                <af:button text="Get Value" id="b2"
                           actionListener="#{viewScope.GetValueProgCompBean.getValueOfCompAction}"/>
                <af:panelGroupLayout id="pgl1" layout="vertical"
                                     binding="#{viewScope.GetValueProgCompBean.parentGroupBind}">
                    <af:spacer width="10" height="10" id="s2"/>
                </af:panelGroupLayout>
            </af:form>
        </af:document>

To create components at run time i have used same approach described in above blog post
Check the code written on Create Components button

import javax.faces.component.UIComponent;
import javax.faces.event.ActionEvent;

import oracle.adf.view.rich.component.rich.input.RichInputText;
import oracle.adf.view.rich.component.rich.layout.RichPanelGroupLayout;
import oracle.adf.view.rich.context.AdfFacesContext;

    //Binding of panel group layout , it will be parent of prog. created components
    private RichPanelGroupLayout parentGroupBind;

    public void setParentGroupBind(RichPanelGroupLayout parentGroupBind) {
        this.parentGroupBind = parentGroupBind;
    }

    public RichPanelGroupLayout getParentGroupBind() {
        return parentGroupBind;
    }

    /**Method to add child components to parent
     * @param parentUIComponent
     * @param childUIComponent
     */
    public void addComponent(UIComponent parentUIComponent, UIComponent childUIComponent) {
        parentUIComponent.getChildren().add(childUIComponent);
        AdfFacesContext.getCurrentInstance().addPartialTarget(parentUIComponent);
    }

    /**Method to create Input text at run time
     * @param actionEvent
     */
    public void createComponentsAction(ActionEvent actionEvent) {
        //Create an Object of desired UI Component
        RichInputText ui = new RichInputText();
        //Set properties
        ui.setId("rit1");
        ui.setLabel("Input text 1");
        ui.setContentStyle("font-weight:bold;color:red");
        //Now add this component to any parent component
        addComponent(getParentGroupBind(), ui);

        RichInputText ui1 = new RichInputText();
        ui1.setId("rit2");
        ui1.setLabel("Input text 2");
        ui1.setContentStyle("font-weight:bold;color:red");
        addComponent(getParentGroupBind(), ui1);
    }

Now run application and click on button , you will see two inputText are created

Now to get value of these components follow the steps
1. Get Parent layout
2. Iterate over parent to get all child components
3. Get Value of every child

See the code written on get value button in managed bean

    /**Method to Iterate over parent and get value of all child components
     * @param actionEvent
     */
    public void getValueOfCompAction(ActionEvent actionEvent) {
        RichPanelGroupLayout PF = getParentGroupBind(); // Get Parent Layout
        List<UIComponent> listcomp = PF.getChildren(); // Get all child
        Iterator iter = listcomp.iterator(); // Create an Iteraotr to iterate over childs
        while (iter.hasNext()) {
            UIComponent comp = (UIComponent) iter.next(); // Get next Child Component
            System.out.println("Component is-" + comp + " and value is-" +
                               comp.getAttributes().get("value")); //Get Component detial and it's value
        }
    }

Again check , enter value in both inputText and click on button to get value

Output on console-

ADF Skinning : Change color and style of af:query buttons in ADF Faces (Jdev 12.1.3)

Hello All,

This is another post about ADF Skinning , in this post i am going to show you that how can we change button's style in af:query component
Actually this is very easy , if we define some styles for af:button component in our css file then it will be applicable on af:query's buttons (Search, Reset, Advanced, Save etc) too

Suppose i have defined this in css file

af|button{
    color:navy;
    font-weight:bold;
}

Now it will change color of all buttons of application including af:query
See this snap after applying this skin

But if you have a requirement to use different style in af:query buttons or you don't want to change color of all buttons
Then it is not that much easy as it seems ☺

There is a selector to style buttons of af:query - af|query::button 
But this works only if buttons are af:commandButton not af:button
See from docs-

af|query::button Styles the buttons of the query component. Note that this skin selector is only present when the skin selector -tr-button-type is set to 'old', and the query buttons are rendered as af:commandButtons. When the -tr-button-type is set to 'unified', the query buttons are rendered as af:buttons and have the default stylings for af:button applied, so that query buttons have the same look and feel as all other buttons. Tip: If you skin this selector's background-image, you may also want to skin it for :hover, :active, :focus. The :disabled state is currently not supported. Please note that for buttons :active and :focus pseudo-classes do not work in IE7. IE7 also does not allow disabled buttons to be styled. It is recommended that you use the .AFButton*:alias selectors as a shortcut to skin all button components the same.

So for this first i have to change -tr-button-type selector to old so that i can use af|query::button
Now see the css

af|query {
    -tr-button-type: old;
}
 af|query::button {
    color: red;
    font-weight:bold;
}

 af|query::button:hover {
    color: Orange;
    font-weight:bold;
}

 af|query::button:focus {
    color: maroon;
    font-weight:bold;
}

af|button{
    color:navy;
    font-weight:bold;
}

Check the output-

To use specific style for af:query you can create styleClass in css file and put this in styleClass property of af:query
Suppose i have two af:query components on page and i want to use different style for both
For this i have define two different styleClass in css file like this-

af|query {
    -tr-button-type: old;
}
 .mystyle1 af|query::button {
    color: red;
    font-weight:bold;
}

.mystyle2 af|query::button {
    color: darkgreen;
    font-weight:bold;
}

and on page put myStyle1 in styleClass property of first af:query component and myStyle2 in second af:query
See how it looks now -

Cheers, Happy Learning  ☺

ADF Skinning : Remove "search" or "more" link from af:inputComboboxListOfValues in ADF Faces (Jdev 12.1.3)

Hello all,

This post is about a small CSS trick that may be useful sometimes

we often use af:inputComboboxListOfValues to show large amount of data as List of Values
From Oracle Docs-
The inputComboboxListOfValues component allows a user to open a choice list and select from a list of values, in order to populate the LOV field (and possibly other fields) on a page.
Users can either select a value from the list in the dropdown panel or click the "Search..." link at the bottom of the panel to launch the "Search and Select" dialog. The dialog enables users to search for specific values and select the desired value that should go into the LOV field on the base page. The choice list when opened could display various items in the following order with separators between each (if applicable).



Have a look at this -

 here you see a link "more" on click this link a search dialog box appears , when you define a search criteria in lov at model level then this link appears as "search"

So to remove this link from combobox use this CSS

af|inputComboboxListOfValues::search{
    display: none;
}

Now look at combo box , we are done

Build selectOneChoice to show hierarchical (tree style) data programmatically in ADF

This post is based on an old article from Frank Nimphius How - to build a select one choice displaying hierarchical selection data

This article is about showing tree structure data in af:selectOneChoice component using ADF BC , it makes use of tree binding and af:forEach
Same concept i have used to populate data from managed bean using List data structure

Let's see the implementation part - how to populate tree style selectOneChoice programatically ?

First we have to design a Java Bean class in such a way that it can hold  master -detail type of data

A class that represents a List for Parent Values
                          ======> A list of same type to hold Child Values

See bean class code-

import java.util.ArrayList;
import java.util.List;

public class Seasons {
    public Seasons(String name) {
        this.name = name; // To Store Header Values (Storing Seasons Name :))
    }
    // Season and Charater Name
    private String name;
    // To Store Detail Values (Storing Season's Charatcers)
    private List<Seasons> characters = new <Seasons>ArrayList();

    public void setCharacters(List<Seasons> empDet) {
        this.characters = empDet;
    }

    public List<Seasons> getCharacters() {
        return characters;
    }


    public void setName(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
    // This methods directly add characters value in list
    public void addCharaters(Seasons employee) {
        characters.add(employee);
    }
}

Now how to use this bean in managed bean to add records, i have written code in constructor to populate values on class load

    // Master List to populate data in selectOnce choice
    List<Seasons> seasonList = new ArrayList<Seasons>();

    public void setSeasonList(List<Seasons> seasonList) {
        this.seasonList = seasonList;
    }

    public List<Seasons> getSeasonList() {
        return seasonList;
    }
    //Constructor of Managed Bean to populate data on page load (you can move this code )
    public TreeStyleLovBean() {
        super();
        // Creating tree for Seasons and Characters details
        // Adding Master Values (seasons)
        Seasons season1 = new Seasons("Game of Thrones");

        // Adding Detail Values (Child Node-Characters)
        Seasons character = new Seasons("Tywin Lannister");
        season1.addCharaters(character);
        character = new Seasons("Tyrion Lannister");
        season1.addCharaters(character);
        character = new Seasons("Jaime Lannister");
        season1.addCharaters(character);
        character = new Seasons("Cersie Lannister");
        season1.addCharaters(character);
        character = new Seasons("Ned Stark");
        season1.addCharaters(character);

        // Adding Master Values (seasons)
        Seasons season2 = new Seasons("Arrow");

        // Adding Detail Values (Child Node-Characters)
        character = new Seasons("Oliver Queen");
        season2.addCharaters(character);
        character = new Seasons("Moira Queen");
        season2.addCharaters(character);
        character = new Seasons("Laurel Lance");
        season2.addCharaters(character);
        character = new Seasons("Sara Lance");
        season2.addCharaters(character);

        // Adding Master Values (seasons)
        Seasons season3 = new Seasons("Vikings");

        // Adding Detail Values (Child Node-Characters)
        character = new Seasons("Ragnar Lothrak");
        season3.addCharaters(character);

        // Adding Master Values (seasons)
        Seasons season4 = new Seasons("The Flash");

        // Adding Detail Values (Child Node-Characters)
        character = new Seasons("Barry Allen");
        season4.addCharaters(character);
        character = new Seasons("Harisson Wells");
        season4.addCharaters(character);
        character = new Seasons("Iris West");
        season4.addCharaters(character);
        character = new Seasons("Joe");
        season4.addCharaters(character);

        // Adding all list to topList
        seasonList.add(season1);
        seasonList.add(season2);
        seasonList.add(season3);
        seasonList.add(season4);

    }

how to bind this managed bean to selectOneChoice ? i have used same concept as described in Frank's article using af:forEach

<af:selectOneChoice id="selectBox" label="Choose Character" valuePassThru="true"
                                        styleClass="employeeSelectBox" contentStyle="width:150px;"
                                        binding="#{viewScope.TreeStyleLovBean.selectOneValueBind}">
                        <af:forEach items="#{viewScope.TreeStyleLovBean.seasonList}" var="seasonNm">
                            <af:selectItem label="#{seasonNm.name}" disabled="true" id="si1"/>
                            <af:forEach items="#{seasonNm.characters}" var="characterNm">
                                <af:selectItem label="#{characterNm.name}" value="#{characterNm.name}" id="si2"/>
                            </af:forEach>
                        </af:forEach>
                    </af:selectOneChoice>

you can see here that first forEach is populated from master list and iterates over list of seasons and first selectItem show season's name
the inner forEach makes used of character list that is defined in Java Bean class and stores season wise character's name
Rest is same - a CSS is used to differentiate color and alignment of parent and child records (same as Frank's article)

<f:facet name="metaContainer">
                <af:group>
                    <![CDATA[
<style>
.employeeSelectBox option{text-indent:15px;color:darkgreen;}
.employeeSelectBox option[disabled]{color:red; background-color:#dddddd; 
font-weight: bold; text-indent:0px}
</style>
]]>
                </af:group>
            </f:facet>

Now run this application - see how it appears on page

It looks quite good :) to get selected value in bean just use componentBinding.getValue();

Show uploaded file (pdf/text/html/xml/image) content on page -Oracle ADF

Hello all
In previous post
Uploading and downloading files from absolute server path in Oracle ADF (12.1.3)
we saw that how can we upload any file to absolute server path and download same from there.
Uploading part is done using simple java code to write file to specified folder and downloading part is done using <af:fileDownloadActionListener>

Now in this post i am going to show that how can we display a file on page directly without downloading it.
So for this i am using same sample application that i have used in previous post , you can download it from here



See the additional steps to show file content on page-

• Create a servlet to parse file into output stream , this output stream will be used to show file content further.
  To create servlet right click on viewController project select New--->From Gallery-->Web Tier-->Servlet











• See servlet source code to parse file into outputStream



import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.PrintWriter;

import javax.servlet.*;
import javax.servlet.http.*;

public class PreviewFileServlet extends HttpServlet {
    private static final String CONTENT_TYPE = "text/html; charset=UTF-8";

    public void init(ServletConfig config) throws ServletException {
        super.init(config);
    }

    /**
     * @param request
     * @param response
     * @throws ServletException
     * @throws IOException
     */
    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String path = (request.getParameter("path"));

        OutputStream os = response.getOutputStream();
        //If path is null
        if (path.equalsIgnoreCase("No")) {
            path = "D:\\Document\\ItemImage\\Item.jpg";
        }
        if (request.getParameter("path") == "") {
            path = "D:\\Document\\ItemImage\\Item.jpg";
        }
        InputStream inputStream = null;

        try {
            File outputFile = new File(path);
            inputStream = new FileInputStream(outputFile);
            BufferedInputStream in = new BufferedInputStream(inputStream);
            int b;
            byte[] buffer = new byte[10240];
            while ((b = in.read(buffer, 0, 10240)) != -1) {
                os.write(buffer, 0, b);
            }

        } catch (Exception e) {

            System.out.println(e);
        } finally {
            if (os != null) {
                os.close();
            }
            if (inputStream != null) {
                inputStream.close();
            }

        }
    }
}



• Now open page in editor and drop an af:inlineFrame from component palette . inlineFrame is used to create a frame to show any external page or document just like as HTML iframe , it is loaded from source attribute
  So here i am using servlet as source attribute for this inlineFrame



<af:inlineFrame id="if2"
                                                    source="/previewfileservlet?path=#{bindings.Path.inputValue == null ? 'No' : bindings.Path.inputValue}"
                                                    inlineStyle="height:350px;width:800px;" sizing="preferred"/>


here path of document is added to pageDef bindings that is passed to servelt as parameter


• Now run this application and check it
