[away3d] ObjectContainer3D parent Object3D

[metSyS]

I have some Cubes which are owned by ObjectContainer3D. I want to
listen all of this objects throught "parent", but can't understand how
can I do it.

some function which creates this cubes :

private function createCubes():void
{
 for (var i:int=0; i<15; i++)
 {
  cubeArray[i]=new Cube();
  cubeArray[i].x=120-(i*50);
  group.addChild(cubeArray[i]);
 }
}

and I want to listen all these cubes, and tween that cube on which is
mouse over up throught Caurina, and want to know it index

group.addOnMouseOver(addOnMouseOverObject);

private function addOnMouseOverObject(e:MouseEvent3D)
{
 searchPhotoIndex(e.target);
}

private function searchPhotoIndex(searchElement:Object3D):void
{
        for (var i:int=0; i<16; i++)
        {
                if (cubeArray[i]==searchElement)
                {
                        searchPhotoIndexVar=i;
                }
        }
}

So, how can I know index of this cube?
