Carlin Rogers resolved BEEHIVE-1214.
------------------------------------
Resolution: Fixed
Fix Version/s: V.Next
Assignee: Carlin Rogers
This is fixed with svn revision 611318. I changed the nested page flow creation
to persist the page flow in the session and then initialize it (including the
controls, so that the PageFlowController @Context member fields in controls are
initialized correctly).

> The PageFlowController @Context in controls are not initialized correctly in
> nested page flows. The context is set to the parent page flow rather than the
> nested page flow instance. I think the issue occurs where we create the
> nested page flow instance.
> The usual steps for handling a request to a new page flow are to persist the
> new page flow as the "current" page flow, then do the page flow
> initialization which includes initializing the controls. When the controls
> are initialized, the new control has already set as the "current" page flow
> so the controls context for the "current" page flow controller is correct.
> However, in FlowControllerFactory.createPageFlow() when the new page flow
> instance is nestable, we first go through the initialization before calling
> persistInSession(). That means the "current" page flow controller is the
> parent controller and not the new instance.
> There is a workaround. Rather than use the actual context member in the
> control, the control implementor could get the PageFlowController from the
> contextual services...
> @Context
> private ControlBeanContext _context;
> ...
> _context.getService(PageFlowController.class, null)
> I'll add some files that can be used to dump state during the control and
> page flow life cycle when changing from parent to a nested page flow
> controller. Will help to debug and test.
