Forgive the dense noob here, but how is the type info lost? I thought that by subclassing CairngormEvent you get basic checking and then you can just do a cast or 'event as MyCutomEvent' inside the execute method. I guess I am just not clear on what the issue is and where the problem lies. Can someone edumacate me?

I know Steven didn't really dig this idea, but if you case the type, you can compare to the Event's constant like: > > public static const EVENT_DOSOMETHING:String = "doSomething"; > > function execute(event:CairngormEvent) > { > switch(event.type) > { > case MyEvent.EVENT_DOSOMETHING: > someMethod ( MyEvent(event).someTypeSafeProp); > break; > } > } > > > ----- Original Message ----- > From: Ralf Bokelberg > To: [email protected] > Sent: Thursday, July 27, 2006 4:20 PM > Subject: Re: [flexcoders] Re: cairngorm Events and data payloads > > > The only typesafe solution i can think of, is to abandon CairngormEvents and replace them by methods of the FrontController. Most of the apps i've seen so far don't make use of the runtime changeability anyways.
