why would a dispatch fail?

Hi,

I've been reworking my proof-of-concept demo with Robotlegs, and am several days in with good success so far. However, I've hit my first brick wall. The call to dispatch in the code below returns false, and the command is not instantiated.

        var pev:PlayerEvent = new PlayerEvent(PlayerEvent.SEEK, this.player);
        var ret:Boolean = dispatch(pev);

What is especially strange is that almost identical syntax is working perfectly elsewhere in the same mediator.

The API has no explanation of why a call to dispatch() might fail. Your help is much appreciated!

Thanks,
Peter

   Oops -- please ignore this post! With my newbie eyes I stared right past the fact that the syntax in the context class is event-specific. I was missing:

   commandMap.mapEvent(PlayerEvent.SEEK, PlayerCommand, PlayerEvent, false);

   Somehow it magically works that posting a discussion corrects the vision.

   Sorry for any distraction and thanks anyway!

   Hi Peter,

   Dispatch will return false if there is no listener for the event:

   http://github.com/robotlegs/robotlegs-framework/blob/v1.0.3/src/org...

   So, it would seem that there is no Command (or other listener) bound to this event on the event bus.

   Ah, cool, glad you're sorted.
