Hi,
This is the approach i was trying to explain in the previous email.
It was just so your VO doest have to extend EventDispatcher.
Not sure why your getting an id error though.. Perhaps stepping through
the code with the debugger will help.

I notice that one is called _evtDispatcher and the other
_customEvtDispatcher, not sure if thats the real code or not though or
just example code.
