Paramater event

Question

Ok I get an error when getting variable from e event  Access of possibly undefined property 'A' through a reference with static type flash.events:Event.
this si what I have
//main   myplayer.addEventListener("eventClicked",eventClickedHandler);   private function eventClickedHandler(e:Event):void {
trace( "Object = " + e.A ); //error        }
      //player
private var  myevent:ClassEvent;
private var  a:int ;   public function goEvent():void{
a=4;
dispatchEvent( new ClassEvent( "eventClicked", a ) );
 //event
package  {
      import flash.events.Event;       public class ClassEvent extends Event
             public var A:int ;             public function ClassEvent( str:String, a:int, bubbles:Boolean=false, cancelable:Boolean = false )
                     super( str, bubbles, cancelable );
                    this.A = a;
            override public function clone():Event
            return new ClassEvent(type, A, bubbles, cancelable);

private function eventClickedHandler(e:ClassEvent):void {
