Hi
I checked the stacktrace and the code looks good. There are not recent
changes that could affect in that location.
The issue should be caused by a listener that is not restored
correctly. Take a look at your <f:event listener="..", @ListenerFor
annotations. One suposition is you have registered a listener in a
renderer using @ListenerFor or you have registered programatically a
renderer as a listener, but the renderer does not belong to the same
component and the restore code (see the line for restore renderer):
//Full restore
listenerCapability = (Integer) values[2];
if ((listenerCapability & LISTENER_TYPE_COMPONENT) != 0)
{
listener = UIComponent.getCurrentComponent(context);
}
else if ((listenerCapability & LISTENER_TYPE_RENDERER) != 0)
{
listener = (ComponentSystemEventListener)
UIComponent.getCurrentComponent(context).getRenderer(context);
}
else
{
listener = (ComponentSystemEventListener)
UIComponentBase.restoreAttachedState(context, values[1]);
}
will cause a class cast exception. If that's the case, please let us
know the use case to add the additional check and force save the
renderer class in such cases. In other case, to solve this issue it is
necessary provide a test case.

Leonardo Uribe
