Custom Selection Listener for ADF Table

In this post I will be describing how we can  have a custom selection listener for ADF Table. By default when we drag and drop a ADF Table Component, it gives us the option to select a row. If that option is selected, it creates a default selectionListener for the table component that is
#{bindings.VO.currentModel.makeCurrent"} where Iterator is VO iterator. This operation synchronizes the current selected row with the Iterator to which this Tree Binding is pointing to.

In Addition to this it also adds a attribute selectedRowKeys which has a value
#{bindings.VO.collectionModel.selectedRow}. This makes the selected row from the collection.

But when you change this to your custom selection handler of your managed bean, then the operation which are performed by {bindings.Iterator.currentModel.makeCurrent"} and selectedRowKeys needs to be done programmatically.

One way is to invoke #{bindings.VO.currentModel.makeCurrent"} programmatically in the selectionListener of the managed bean. This has been explained very clearly by my friend Ashish Awasthi :- Custom Selection Listener



In this article I will go through a different approach to implement custom selection listener.

Lets create a ADF project using HR Schema and create DepartmentsVO.

After that create a JSPX page and drag the VO as a table and select singe row selection. Now change the selectionListener to point to managed bean and create a selectionListener method. Also remove the selectedRowKeys attribute from the table as we will be doing this programmatically.

The Table should look like below:

In the managed bean, there are two methods. One is onTableRowSelection and customListener. 

customListener is what binded to the selectionListener from table component and onTableRowSelection method has actual logic to make the current row of the table as selected.

Below is the code in the bean.

After onTableRowSelection set the current Row , customListener gets the current row and access its department name.

Thats all. Lets run the page.

On Selecting Public Relations, we get output in the consoles as same name.

Thats it.
