Thank you for your response.
I still have a problem. I get a DanglingReferenceException when I put
updateNodeReferences() in my behavior.
Would it be possible to refer me to an example of cloning a Behavior, or
show me what the cloneNode and updateNodeReferences functions should look
like for this simple example.

Hi Dave,
You should use the following callback to retrieve the cloned copy of
TransformGroup which Behavior refer to:
public void updateNodeReferences(NodeReferenceTable referenceTable) {
super.updateNodeReferences(referenceTable);
newTransformGroup = (TransformGroup)
referenceTable.getNewObjectReference(oldTransformGroup);
....
}
