title: keyboard event as3 not working
body: <p>This was something that had me banging my head for 2 hours before I figured it out.<br>
  I decided to post it here, to help others not pull their hair out :).</p>
  
  <p>Essentially the bug was I was not receiving the keyboard event from within my flash builder environment (The same bug/issue is visible with adobe flash cs5). I set the stage.focus = stage, did not help. I added other event listeners (mouse_down, frame_enter) which worked fine, I added MovieClip children and listened for events on those children, still the same issue.  </p>
  
  <pre><code>package
  {
    public class Test extends Sprite 
    {
  
      public function Test() 
      {
          this.addEventListener(Event.ADDED_TO_STAGE,init);
      }
  
      public function init(stage:Stage):void 
      {
          this.removeEventListener(Event.ADDED_TO_STAGE,init);
          stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);
          stage.addEventListener(KeyboardEvent.KEY_UP, keyReleased);
      }
  
  
      private function keyPressed(e:KeyboardEvent):void 
      {
          trace("keyPressed");
      }
  
      private function keyReleased(e:KeyboardEvent):void 
      {
          trace("keyReleased");
      }
    }
  }
  </code></pre>
