Yes, TALES traversal. Actually I didn't even get to see the object
through the web because the error occured in the view method.

No I hadn't, but I should have ! Thanks for the idead, for my needs it
does the job perfectly.

I believe it's wrong too, but at this point there's too much voodoo in
these parts of Zope that it'll take Zope 3 to clean all that up :)

I'm assuming you're using TALES traversal as opposed to ZPublisher 
traversal, right?  It lets you view the objects directly through the 
web, doesn't it?

Have you considered implementing __getitem__() instead of 
__bobo_traverse__()?  __bobo_traverse__() is messy.  I'm inclined to 
tell you the restrictedTraverse() method is wrong, and that container 
should be computed as the aq_inner of the aq_parent, but we something 
might depend on the current behavior.
