Создать свое событие, и передавать ему нужные данные

package  {
	import flash.events.Event;
 
 
	public class MyEvent extends Event {
 
		public static const SOME_TYPE:String = "someType";
		public var someVar:Object = null;
 
		public function MyEvent(type:String, bubbles:Boolean=false, cancelable:Boolean=false) { 
			super(type, bubbles, cancelable);
 
		} 
 
		public override function clone():Event { 
			var event:MyEvent = new MyEvent(type, bubbles, cancelable);
			event.someVar = this.someVar;
			return event;
		} 
 
		public override function toString():String { 
			return formatToString("MyEvent", "type", "bubbles", "cancelable", "eventPhase"); 
		}
 
	}
 
}

ну и отправлять как-то так:

var event:MyEvent = new MyEvent(MyEvent.SOME_TYPE);
event.someVar = something;
dispatchEvent(event);
