OK, my contribution. Sometimes ytou want your ObjectManager to only be able to contain certain types of objects. The question is what the best method to do this is. What I did was, in this case limiting to Images and files: def all_meta_types(self): """ """ return filter(lambda d, m=('Image', 'File'): d['name'] in m, ObjectManager.all_meta_types(self)) -- Itamar S.T. itamars@ibm.net
