Hi I'm new to Zope and have a problem with permissions on a zope site. If I unchecks the Aquire permission settings (APS) for one of the Instances and checks the permission to Owner, none of the instances works. Expample: if I changes the APS for instance_1, loggs in with Owner2 and accesses instance_2 it does not work. The function with the permission is to let the owner view and run his instance, but none of the other instances. The site structure: Root Folder -Products --ProductName ---ClassName -Site (Security: APS on all) --SubFolder (Security: APS on a few, manager on the rest, none on owner, User has Access contents information, Change Configuration, View) ---Instances_1_of_ClassName Owner1 (Security: APS on all, else it does not work) ---Instances_2_of_ClassName Owner2 (Security: APS on all, else it does not work) ---Instances_3_of_ClassName Owner3 (Security: APS on all, else it does not work) ---Instances_4_of_ClassName Owner4 (Security: APS on all, else it does not work) ---Instances_5_of_ClassName Owner5 (Security: APS on all, else it does not work)
