Hi there, Ok so I have a class that has multiple inheritance. My main class (A) works fine, but I wanted to add in folderish properties. The problem is the order of multiple inheritance and viewing folder objects. When you view a folder from you call index_html and this gives a content list. By inheriting this way: class B(A, Folder): I have kept all my A methods. However viewing it does not produce the content list since its overwritten by A. Of course inheriting: class B(Folder, A): Does work for that, but breaks all my other methods. Solutions: Well I tried defining a tab - view_folder which was something along the line of: def view_folder(self, client=None, REQUEST={}): ''' doc string ''' return Folder(self, client, REQUEST) But get an attribute error on manage_tabs. Any ideas? Thanks. -- Andy McKay, Developer. ActiveState.
