[away3d] MovieClipSprite clickable as object3D

[Kosma]

Hello, I've been trying to come to grips with the nature of
MovieClipSprite. I'm trying to be able to click on a MovieClipSprite
as a 3D object, so that I can access it's parent container. Can anyone
help out?

txt.text = "HEADER";
txt.background = true;
txt.autoSize = TextFieldAutoSize.LEFT;
txt.selectable = false;

var clip:MovieClip = new MovieClip();
clip.addChild(header);
var button:MovieClipSprite = new MovieClipSprite(clip);

button.addEventListener(MouseEvent3D.MOUSE_DOWN,objectClick);

private function objectClick(e:MouseEvent3D):void{
trace(click);
}
