If you're extending UIComponent, you already have a "move" event
declared to be of type mx.events.MoveEvent. The MXML compiler
generates an event handler that accepts an argument of type
mx.events.MoveEvent. So now when you pass it an object that is not a
MoveEvent (i.e. flash.events.Event), you get a runtime error.
I think the MXML compiler should give an error if the same event is
repeated in a subclass with an incompatible type.
