adjustments to the UIXComponentBase subscribeToEvent and unsubscribeFromEvent
implementation
--------------------------------------------------------------------------------------------
Key: TRINIDAD-2230
URL: https://issues.apache.org/jira/browse/TRINIDAD-2230
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 2.0.1-core
Environment: n/a
Reporter: Gary VanMatre
These new JSF 2 methods on the UIComponent (subscribeToEvent and
unsubscribeFromEvent) has a very strange contract. The formal parameter for
the listener is of type ComponentSystemEventListener. However, the method to
query for the registered listeners getListenersForEventClass returns a list of
SystemEventListener. The ComponentSystemEventListener and SystemEventListener
do not have a common heritage so the subscribeToEvent and unsubscribeFromEvent
creates a wrapper that implements the SystemEventListener.
Since the resultant objects from getListenersForEventClass are a wrapper, there
is no way to determine if the original listener added by calling
subscribeToEvent is in the list of wrapper objects since the wrapper is a
private nested class and doesn't necessary implement the
ComponentSystemEventListener interfaces.
