Subject [jira] Created: (BEEHIVE-1104) ControlException thrown during shared flow onCreate() when control has a PageFlowController contextual service.
Date Mon, 17 Apr 2006 20:39:18 GMT
ControlException thrown during shared flow onCreate() when control has a PageFlowController
contextual service.
---------------------------------------------------------------------------------------------------------------

         Key: BEEHIVE-1104
         URL: http://issues.apache.org/jira/browse/BEEHIVE-1104
     Project: Beehive
        Type: Bug

  Components: NetUI  
    Versions: 1.0.1    
    Reporter: Carlin Rogers


Controls that use the PageFlowController contextual service in a shared flow, do not get initialized
correctly during the shared flow onCreate() life cycle method. The Shared Flow objects for
a given page flow are created before the PageFlowController. Therefor, when a shared flow
makes a call to an @Control control (that has a @Context PageFlowController context) from
within the shared flow's onCreate() method, the PageFlowController contextual service will
not yet be available. The generated control bean impl initializer method initServices() throws
the ControlException when it cannot get the contextual service.

However, in a follow up call to the shared flow that requires use of the control, there is
another call to ControlBean ensureControl() which will successfully find the PageFlowController
contextual service and the initialization will be complete. The shared flow will still function
correctly.

Here's a stack trace...
