Passing Parameters from ADF Task Flow with Fragments into ADF Bounded Task Flow

It is a common use case to pass parameters from ADF Task Flow with fragments into another ADF Task Flow without fragments. I got this question for my previous blog post - Parent Action Activity in ADF Task Flow. The use case:http://www.blogger.com/img/blank.gif

1. We have ADF Bounded Task Flow, it contains two main elements - page P1 and another ADF Task Flow call - C1
2. Page P1 included ADF region, this region comes from ADF Task Flow with Fragments
3. We need to pass parameter from ADF region available in P1 into ADF Task Flow call C1

ADF Task Flow in JDeveloper 11g

In JDeveloper 10g there is only one possibility to design application page flow structure - using JSF navigation flows. But sometimes, use cases require to implement complex page flow, that is not supported by JSF navigation flows. JDeveloper 11g brings ADF task flows in addition to JSF navigation flows. From Oracle JDeveloper 11g Technology Preview, Fusion Developer's Guide for ADF:

Task flows provide a more modular and transactional approach to navigation and application control. Like standard JSF navigation flows, task flows mostly contain pages that will be viewed. However, instead of describing navigation between pages, task flows facilitate transitions between activities. Aside from navigation, task flow activities can also call methods on managed beans, evaluate an EL expression, or call another task flow, all without invoking a particular page. This facilitates reuse, as business logic can be invoked independently of the page being displayed.

TrackQueryPerformed Property Usage and ADF Task Flows

I will describe following scenario - two ADF Task Flows, second ADF Task Flow is opened as Isolated. First ADF Task Flow provides query functionality implemented as View Criteria, and second ADF Task Flow accepts current row key value and allows to edit data. Scenario is pretty simple, and can be implemented in Oracle ADF very fast. However, there is one trick if you open second ADF Task Flow as Isolated. I will describe it and provide solution.

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:click here detail read post
