Hi Richard,
I unfortunately didn't manage to find a solution before my vacations, but I 
now had more time and found a way around the multiple event1 dispatches.
You can get it from trunk (rev. 74109).
This, combined with your event5 deferring the UML way, will now get you the 
expected behaviour.

HTH,
Christophe
