Error using the ModelData.fromBinary function in the framework

Question

I have a collada file with animation.
this is how i load and proces it:
public var loader:ColladaLoader;
public function load(url:String):void {
          loader = new ColladaLoader( url );
          loader.addEventListener( Event.COMPLETE, onLoaded );
private function onLoaded(event:Event):void {
  manifest   = loader.model.addTo( scene );
          animations = loader.model.animations;
          for each ( var anim:AnimationController in animations ) {
                    anim.bind( scene );
It  all works fine!
But because the collada is a realy big file, i thought to use the fromBinary and toBinary functions.
It should be possible to do this.
private function onLoaded(event:Event):void {
          //manifest   = loader.model.addTo( scene );
          //animations = loader.model.animations;
          // create the binary
          var ba:ByteArray = loader.model.toBinary();
          // recreate the ModelData.
          var md:ModelData = ModelData.fromBinary(ba);
          // add to sceneNode.
          md.addTo(scene);
But this error is thrown:
          [Fault] exception, information=Error: Unsupported Element Type
this is fired somewhere from the GenericBinary classes.
Can someone (from adobe help me on this one).
Is it possible to use 'fromBinary' and 'toBinary' with collada files?
When i load a OBJ file it goes well.

Hi,
I dont understand why would you need to use the "bpws:getVariableData" function.
When you are mapping a source-node to a target-node, it usually assigns the value in the source-node to the target-node, which is as good as using the "bpws:getVariableData" function.
So, technically speaking you need to use this function explicitly to achieve that ...
Also, if you want the instance-id, you can use the "ora:getInstanceId()" directly in the BPEL code than using it in the transformation.
