---------------------------------------------------------------
I've listed a work around below add it to any class you wish that utilizes the
EventDispatcher(pretty much every class). It overrides a few methods to
duplicate the functionality of the original EventDispatcher while adding in the
new methods.
The original EventDispatcher is part of flash.events (something Adobe has
control over not Apache Flex). We may have a partial solution in the future,
but cannot get at the root of it without a successful ticket with Adobe.
