I expected you to be right, so I tried a simple method like this:

    security.declarePublic('foo')
    def foo(self):
        """Test method"""
        return self.aq_parent.absolute_url()

When called through the web, it displays the URL for the parent of the instance
that defines foo, not the object on which I'm calling the method.  Aargh!
