[flexcoders] flash component in flex issue

[j2me_soul]

  




I got another problem. 
In flex I can only reference the flash button by its ID property.
Most of the time I can't know its ID. I need cover it to a super class like 
MovieClip Instead of that.
How can I fix this ?
 
 <mx:Script>
  <![CDATA[
   private function clickHandler(event:MouseEvent):void
   {
      /* not work */
    MovieClip(event.target).gotoAndPlay(MovieClip(event.target).currentLabel);
     /* only this way can run */
    query.gotoAndPlay(query.currentLabel);
   }
  ]]>
 </mx:Script>
 <local:intergratedQueryButton id="query" click="clickHandler(event)" x="305" 
y="500"/>
