Applying a mask to a custom IconItemrenderer icon

Question

Hi,
I've made a subclass of IconItemRenderer in order to change the label and icon positions. I've done it without problems but i want to apply a png mask to the icon. I´m doing it with this code:
override protected function commitProperties():void
                              super.commitProperties();
                              [Embed(source="assets/circulo_personas160.png")]
                              var imagenMascara:Class;
                              var imgObj:Bitmap= new imagenMascara() as Bitmap;
  imgObj.bitmapData = imgObj.bitmapData.clone();
iconDisplay.mask = imgObj as DisplayObject;
and also I tried this:
override protected function commitProperties():void
                              super.commitProperties();
  var square:Sprite = new Sprite();
                              square.graphics.beginFill(0xFF0000);
                              square.graphics.drawRect(0, 0, 40, 40);
                              addChild(square);
                              iconDisplay.mask = square;
The app always shows the image I'm assining to the mask propierty instead of the image assigned to the iconField with the mask applied. If I remove this code I can see the iconField Image. It means that all the rest runs fine.
Wich could be the problem?
Thanks in advance.
