Hello All

Previously I have posted about using new DVT component TagCloud to design better UI (Showing TagCloud from ViewObject data) and this post is about getting selected tag value of TagCloud component

To enable selection in TagCloud component first thing is to set selectionMode property single, after that we can create a custom selection listener in managed bean to get selected row 

Show chart for every row of ViewObject using af:iterator in ADF Faces

Hello All

This post is about another use of af:iterator component, When we show Employees ViewObject data as a chart then all Employees appears in a single chart but if requirement is to show separate chart for each department ;) See how can we do it

Here I am using Departments and Employees table of HR Schema, Prepare model using both tables, Default view link is created between departments and employees view object (using department Id)

ADF UI- Using New DVT Component Tag Cloud in ADF 12.2.1.1

In new relaese of Jdeveloper and ADF 12.2.1.1 many new data visualization components are introduced

Here I am talking about <dvt:tagCloud> , this component is used to represent textual data in form of tags. You must have seen tag cloud on many websites to show popular tags or patterns

Add and delete records (Parent/Child) in POJO Based ADF TreeTable

Hello All

Previously I have posted about creating POJO based ADF TreeTable , Get Selected Record from POJO based TreeTable and Traverse POJO based TreeTable

Recently a developer asked me about adding and deleting records in POJO based TreeTable so here goes a new blog post

To add records in af:treeTable first we have to check that if user has selected any parent node then new record will be added under it and if there is no selection then new record will be added as parent node, This is the core concept of this post and all these posts uses same sample application and same 2-Level Tree

ADF Basics: Use transient attribute to show description of selected value in case of input and combo Lov

In ADF often We apply LOV on a ID attribute to show it's Description to user, This works good in case of choice list (selectOneChoice) but if we use Input Text with List of Values (<af:inputListOfValues>) or Combo Box with List of Values (<af:inputComboboxListOfValues>) then after selection ID appears on page instead of  Description like this

So to avoid this we apply LOV on a transient attribute that shows Description and sets ID value DB attribute, See how to implement this

Open af:inputListOfValues popup by calling JavaScript programmatically

af:inputListOfValues provides option to open Lov values in a popup and allow user to search, We can open this popup by clicking on magnifying glass icon

Recently I have seen a thread on OTN forum where user wants to open lov popup on a button click after checking some conditions and also found a post by Frank Nimphius Where he used javascript to open Lov popup on double click of mouse.
So guess what I have done ? ;)
Just called that javascript fucntion programmatically on button click

ADF Basics: Count number of records in LOV using LOV Accessor

Hello All

This post is about a simple requirement - How to count number of records in a LOV ?
I have seen this type of threads on OTN forum so here I am writing about it

We can make use of LOV Accessor to  count number of records in LOV as per selected source viewObject record, Here I am using Departments and Employees table of Oracle HR Schema

Navigate to another page on value change event of ADF input component

Recently I have seen a thread on OTN forum in that user want to navigate from one page to another on valueChangeListener of input component.

First Method-
This is a simple piece of code to perform navigation to specific page , Use it in ValueChangeListener directly

 FacesContext facesContext = FacesContext.getCurrentInstance();
 facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, null, "controlFlowName");

Second Method-
ValueChangeListener fires when value of input component changes but it is not meant for navigation, For navigation we use buttons and links with Action property
But for this requirement we have to be a bit tricky, We can queue button Action on value change listener of inputText to navigate to another page
Now first value change listener will be executed and then it'll queue button action to execute and as final outcome user will be able to navigate

Traverse POJO based ADF treeTable, Get Child nodes of selected parent

Previosuly I have posted about populating af:treeTable programmatically and getting selected records from POJO based treeTable

This post is next in that series and here I am extending same sample application that show a tree of Seasons and it's characters
First we will see How to traverse a POJO based treeTable (Iterate through all nodes of treeTable)

Basic idea is to get treeTable Collection Model and iterate over it to get all nodes value, To get CollectionModel created treeTable component binding in managed bean

How to queue SelectionEvent programmatically, Call af:table Selection Listener programmatically

Hello All

Hope you all are doing good :) 

Previously I have posted about defining custom selection listener for af:table and perform desired operation on selection event of table row

Selection Listener is fired when server receives a selection event from client means whenever user selects a row in table (Selection Event) then server process that event and execute selection listener defined in managed bean

And this post is about creating selection event programmatically without user interaction with table.

In ADF we can queue ActionEvent , ValueChangeEvent and in same manner we can create and queue SelectionEvent programmatically

Get Selected records (Child/Parent) from POJO based ADF treeTable

Hello All
Previously I have posted about creating af:treeTable programmatically using POJO and this the next post in series

In this post I am talking about a very common requirement while using POJO based treeTable
How can we get selected records (child/parent) from POJO based treeTable ?

For this post I am extending same sample application, Till now we have seen that how can we create POJO based treeTable
Now we'll see that how to get it's selected records

Create ADF Choice List and apply selectItems to it programmatically

I hope we all know how to create selectOneChoice using Model layer and previously I have posted about populating selectOneChoice programmatically from bean using ArrayList

Programmatically populate values in a af:selectOneChoice component in ADF

But this post is slight different - It is about creating selectOneChoice component and applying selectItems to it programmatically
There is nothing complicated in this , Just a piece of code is required
Here I have used an ArrayList to set SelectItems and created component binding for af:form to add selectOneChoice as it's child 

ADF Basics: Get display and base value of POJO based SelectOneChoice

Previously I have posted about populating selectOneChoice programmatically using POJO

Programmatically populate values in a af:selectOneChoice component in ADF

and this post is about getting selected value of POJO base selectOneChoice (both display value and base value)

ADF Basics: Call PL/SQL Function with OUT parameter in ADF Application

Previous post was about calling PL/SQL Procedure with OUT parameters in ADF Application
ADF Basics: Call PL/SQL Procedure with OUT parameter in ADF Application

And this post is about calling PL/SQL Function with OUT parameters. Basic difference between a Function and Procedure is that Function must return a value but procedure may or may not return a value
So there is always one OUT parameter in PL/SQL Function

ADF Basics: Call PL/SQL Procedure with OUT parameter in ADF Application

Previously i have posted about calling pl/sql function in ADF Application

ADF Basics: Call PL/SQL Stored function in ADF Application

This post is about calling stored procedure in ADF Application , a very basic requirement.

Sometimes we need to call a procedure that has OUT parameters , these parameters are used to return value from procedure. There may be n- numbers of OUT parameters in a procedure
