[Morten W. Petersen] | Any suggestions? Found the problem. There needs to be a method called user_names in the acl_users folder, which returns all the user ids: """ <params>self</params> user_ids = self.UserSource.getPersistentItemIDs() user_ids2 = [] for id in user_ids: user_ids2.append(id) return user_ids2 """ (Can't understand why I had to use an additional list though). Cheers. -Morten
