Importing *.dae file with texture to papervision 3D

Question

I downloaded the exmaples from http://3dvrm.com/flar/, set up a new Flash Builder Project, made some changes and finally I got my cow on top of the marker BUT just the wireframe, not the texture :-(

The Actionscript-Code looks like

		private function setupDAE():void
		{
			//Load collada model
			collada_model = new DAE();
			collada_model.load("model/cow.dae");
			//And setup it's initial parameters
			collada_model.scale = 40;			
			collada_model.rotationX = 90;		
		}

The DAE shows

<library_images>
	<image id="texture0" name="texture0">
		<init_from>./Cow.png</init_from>
	</image>
</library_images>
<library_materials>
	<material id="material0" name="material0">
		<instance_effect url="#material0-fx" />
	</material>
</library_materials>

Any help?
