[away3d] collada + bitmap material

[wexcell]

Hi,
It's me again ;D

I have weird problem with adding bitmap material to my collada object,
got runtime error (see below):

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

oefHandler is my ENTR_FRAME event where I render a scene

And the code how I load a bitmap

bitmapMaterial = new BitmapFileMaterial('assets/texture/red.jpg');
bitmapMaterial.addEventListener(MaterialEvent.LOAD_SUCCESS,
bitmapCompletedHandler);


private function bitmapCompletedHandler(e:MaterialEvent):void
{
        targetMaterial = model.materialLibrary.getMaterial("Material_001")

        targetMaterial.material = bitmapMaterial;

}
