Convenience Method for Re-dispatching View Events in a Mediator?

This may be more suited for the Google Groups list; but I don't want to add unnecessary noise to that board!

I seems to find writing code to redispatch an event from one of my view components back into the Framework in my Mediators. The code ends up looking like this:

override public function onRegister() : void {
    eventMap.mapListener(myView, ViewEvent.FOO, redispatchEvent, ViewEvent);
}

private function redispatchEvent(event : Event) : void {
    dispatch(event.clone());
}

Is there an opportunity for adding an syntactic sugar to make re-dispatching these View events back into the framework easier, or am I missing something here?

Thanks
jonny.

   Have you tried this:

   eventMap.mapListener(myView, ViewEvent.FOO, dispatch, ViewEvent);

   That functionality is already included - it's just that it's too
   obvious to see. I know that it took a hint in the support area for me
   to see it, at least.

   What you're doing in your redispatchEvent method is exactly what
   dispatch already does for you: It (re-)dispatches an event to the
   Robotlegs event bus. Thus, you can just use dispatch as the event
   handler and be done with it:

   override public function onRegister() : void {
       eventMap.mapListener(myView, ViewEvent.FOO, dispatch, ViewEvent);
   }
   

   In Robotlegs 1.1, that will be simplified to

   override public function onRegister() : void {
       addViewListener(ViewEvent.FOO, dispatch, ViewEvent);
   }

   Well don't I feel foolish! I've just updated the Best Practices document to make mention of this as that's the first place I looked for the answer.

   Thanks guys :)
