That's true, Mike. It is a datatype problem, and I seem to have resolved half of the problem by deselecting 'Include data type' and adding a new output reference in directory to tree.vi (Include Datatype is not selected). I now have a coercion dot on the dir 2 tree VI icon in the top level VI. There still remains a data type problem with the NEW traverse and add.vi though. Can't find a way to resolve all class conflicts through the two VIs.
