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...
