Check the code for your 'Users' object for one of the following methods: - - '__bobo_traverse__' - - '__getitem__' I'm gueessing one of those is resposible for returning the object corresponding to 'asmithS': that object is the "here" (context) for the template. Another (weirder) possibility is the '__before_publishing_traverse__' method, which (if present) gets called when publishing traversal enters an object: it can munge the request arbitrarily.
