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
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.
