Using Multiple Selection (selectManyListbox & selectManyCheckbox component) in ADF

Hello All ,
This tutorial is based on use of selectManyListbox & selectManyCheckbox component in ADF to enable multiple selection.
Both component are same in functionality only somewhat different in look-feel.

Follow steps to use these component -

Create a fusion web application and create business components for Departments table of HR Schema

Now create a page and drop Departments Vo from data control on page as multiple selection (checkbox or listbox)

Now binding for this component is created in page-bindings, add a button on page to get total selected values

See how to get selected values in managed bean, JUCtrlListBinding is used to get selected values

import javax.faces.event.ActionEvent;

import oracle.adf.model.BindingContext;

import oracle.binding.BindingContainer;

import oracle.jbo.uicli.binding.JUCtrlListBinding;   

 public BindingContainer getBindings() {
        return BindingContext.getCurrent().getCurrentBindingsEntry();
    }

    public void getSelectedValue(ActionEvent actionEvent) {

        JUCtrlListBinding listBindings = (JUCtrlListBinding)getBindings().get("DepartmentsView1");
        Object str[] = listBindings.getSelectedValues();
        for (int i = 0; i < str.length; i++) {
            System.out.println(str[i]);
        }
    }

this method works for both listbox and checkbox, i have added all selected departments in a FacesMessage and displayed on page

Select All-

And Check-box component look like this-

Complete code written on 'Get Selected Values' button-

    /**Method to get BindingContainer of page
     * @return
     */
    public BindingContainer getBindings() {
        return BindingContext.getCurrent().getCurrentBindingsEntry();
    }

    /**Method to get Selected Values
     * @param actionEvent
     */
    public void getSelectedValue(ActionEvent actionEvent) {

        JUCtrlListBinding listBindings = (JUCtrlListBinding)getBindings().get("DepartmentsView1");
        Object str[] = listBindings.getSelectedValues();
        StringBuilder saveMsg =
            new StringBuilder("<html><body><b><p style='color:red'>Selected Departments are-</p></b>");

        saveMsg.append("<ul>");
        for (int i = 0; i < str.length; i++) {
            System.out.println(str[i]);
            saveMsg.append("<li> <b>" + str[i].toString() + "</b></li>");
        }

        saveMsg.append("</ul><br>");
        saveMsg.append("</body></html>");
        FacesMessage msg = new FacesMessage(saveMsg.toString());
        FacesContext.getCurrentInstance().addMessage(null, msg);

    }

Clear Selected Values of shuttle component (Reset shuttle) programmatically-Oracle ADF

Hello All ,
you have heard about shuttle component in ADF, it works for multiple selection
to use it -refer my previous blog post
Shuttle Component in Oracle ADF (Allow Multiple Selection)

Sometimes we need to reset shuttle (clear selected values) through our code (managed bean)
so in this post I'm going to explain how to do this with simple piece of code

I have created a simple jspx page and placed Departments (HR Schema) view-object on this page as an af:selectManyShuttle
Created managed bean for a link to clear selected indices of shuttle, see code

    public BindingContainer getBindings() {
        return BindingContext.getCurrent().getCurrentBindingsEntry();
    }

    /**Method to Clear selected value of shuttle (Reset Shuttle)
     * @param actionEvent
     */
    public void resetShuttleAction(ActionEvent actionEvent) {
        BindingContainer bc = this.getBindings();
        JUCtrlListBinding listBindings = (JUCtrlListBinding)bc.get("DepartmentsView1");
        listBindings.clearSelectedIndices();

    }

Now see how it works- when user click on this link ,it will clear all selected indices of shuttle

Changing default text of af:dialog buttons (ok,cancel) in ADF

Hello All,
you all have used pop up component with af:dialog in ADF,
default dialog component look like this inside popup

in ADF there is option to change dialog type , select dialog component and go to property inspector-

But sometimes we need to change default dialog button's text as per our requirement, to do this follow steps mentioned below

Drag a popup having dialog as its child component on page
select af:dialog in structure window and go to property inspector

In property inspector navigate Appearance--->Text

Now set values for Affirmative and cancel text
Now run your application and see-

But it's outcome doesn't get changed as it is static, you can see this in managed bean code, i have created dialog Listener and a cancelListener in managed bean

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;

import oracle.adf.view.rich.event.DialogEvent;
import oracle.adf.view.rich.event.PopupCanceledEvent;


public class DialogListenerBean {
    public DialogListenerBean() {
    }

    public void dialogListener(DialogEvent dialogEvent) {
        FacesMessage msg = new FacesMessage("You have clicked- " + dialogEvent.getOutcome().name());
        FacesContext.getCurrentInstance().addMessage(null, msg);
    }

    public void cancelListener(PopupCanceledEvent popupCanceledEvent) {
        FacesMessage msg = new FacesMessage("You have clicked- cancel");
        FacesContext.getCurrentInstance().addMessage(null, msg);
    }
}

When you click on ok and cancel (with changed text), it will return same outcome that was before changing button's text

Cheers- Merry Christmas :-)
