[ve-dev] Ambiguous ContainerTreeEditPart call

[Gerald Rosenberg <gerald@xxxxxxxxxx>]

Looks like ContainerTreeEditPart#createLayoutPolicyHelper() always calls 
the XXXXLayoutPolicyFactory#getLayoutPolicyHelper(VisualContainerPolicy 
vcp) with a null value for the policy even though the tree part is 
characteristically given a separate helper instance for each container.

Is there a way to identify, by Container, EditPart or 
VisualContainerPolicy, the specific helper instance that the 
ContainerTreeEditPart is requesting?  Would a change to VE to implement 
this be feasible?

At least currently, is EditPartListener.Stub#partActivated(EditPart 
editpart) the preferred way to monitor for selection switches between 
EditParts?

Thanks,
Gerald
