I want to store a reference to folders in a members-object. When I tried
some thing worked and some not. Eg. absolute_url() didn't work at all. How
is that? How can I store a reference to to a folder or another
portalobject in a member-object so that everything of the original object
work as intended. It is not good enought just to store the url, because I
have to call methods on the portalobjects.
