Hi, can't manage security and roles in Zope's root folder any more. I'm not sure if this error came up with upgrading from stable 2.3.1 to 2.3.1b3. Zope on Debian Linux: Zope Version Zope 2.3.1b3 (binary release, python 1.5.2, linux2-x86) Python Version 1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3] System Platform linux2 When clicking on 'security' button in the root folder I get the following error. Any help? Thank you Marcus Traceback (innermost last): File /home/zope/Zope/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /home/zope/Zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/zope/Zope-2.3.0-linux2-x86/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /home/zope/Zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/zope/Zope-2.3.0-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_access) File /home/zope/Zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_access) File /home/zope/Zope-2.3.0-linux2-x86/lib/python/AccessControl/Role.py, line 258, in manage_access (Object: ApplicationDefaultPermissions) File /home/zope/Zope-2.3.0-linux2-x86/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: _normal_manage_access) File /home/zope/Zope-2.3.0-linux2-x86/lib/python/Shared/DC/Scripts/Bindings.py, line 353, in _bindAndExec (Object: _normal_manage_access) File /home/zope/Zope-2.3.0-linux2-x86/lib/python/App/special_dtml.py, line 236, in _exec (Object: _normal_manage_access) File /home/zope/Zope-2.3.0-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 146, in render (Object: _.namespace(valid_roles=valid_roles())) File /home/zope/Zope/lib/python/DocumentTemplate/DT_In.py, line 646, in renderwob (Object: permission_settings) File /home/zope/Zope-2.3.0-linux2-x86/lib/python/AccessControl/Role.py, line 182, in permission_settings (Object: ApplicationDefaultPermissions) File /home/zope/Zope-2.3.0-linux2-x86/lib/python/AccessControl/Role.py, line 177, in <lambda> TypeError: (see above) -- _____________________________________ (0> Marcus Schopen //\ Bielefeld, Germany V_/_ _____________________________________
