In my last post I mentioned the great expression column and accessing the parent. I had some trouble though when passing back thru a webservice the client freaked out with an XML parser error, which is obviously a bug as the XML is fine. But it cant handle the Parent/Child thing, it can manage other types of expression over the WS but not that one.

As Dino Espisito wrote an article on this I mailed him in case he had come across this problem, Im waiting for a reply.
