    Error accessing object inside a viewstack

    marrrrrrrc Level 1
      I'm trying to call this when the application initializes:

      quote:

      public function init():void {
      rtByQueues.addEventListener(ChartItemEvent.ITEM_CLICK, queuesUpdate);
      }


      and getting this error:

      quote:

      TypeError: Error #1009: Cannot access a property or method of a null object reference.

      I figured it out that its because I'm using a ViewStack and rtByQueues columnchart is inside one of those views. How can I do the above when using a viewstack like so:

      quote:

      <viewstack id="views">
      <canvas id="view1">
      <grid><gridrow><griditem>
      <columnchart id="rtByQueues">...........</columnchart>
      and so on....


      I'm using flex 3. Thanks!
