[Zope] SESSION and REQUEST variables

I am storing a TransientObject based instance in a SESSION variable. What are my options for getting the REQUEST variable when calling methods on this instance from a page template? Looking at self.REQUEST doesn't seem to work and using 'python:obj.getData(request)' is very verbose. I would like 'obj/getData' to work, but it doesn't. Kevin Smith Kevin.Smith@theMorgue.org
