PopUpFetch Option for Property Listener

With previous JDeveloper/ADF 11g releases it was quite complicated to catch popup fetch event, we were overriding popup fetch listener inside managed bean and processing it. Its a good hint, things are simpler now - there is popupFetch property with Set Property Listener component:


This means, you can associate Set Property Listener directly with popup, and listener will be invoked automatically on popup fetching.

To demonstrate this functionality I have implemented simple filter solution, filter box is opened inside popup and is initialized with currently selected department data, by default:


Default value for filtering is set through Set Property Listener associated with popup, it assigns currently selected department name:


When user selects another department, filter value is reset by Set Property Listener during popup fetch event:


Filter operation is performed:


Filtering is performed, because VO contains WHERE clause with Bind Variable:


Filter field is mapped with variable defined inside Page Definition:


Page Definition variable is accessed through Attribute Value:
