Hi all, I have found a bug with Transpüarent FolderPatch and ZopeSecurity. Let me explain my structure. root: folder 1: foo: bar: foobar: foo 1: bar 1: Let me say that folder 1 is a normal Folder, foo and bar and foo 1 and bar 1 are orignal TransparentFolders and foobar is my own Product which is a Foder with _is_transparent=1. The problem is, that ONLY if i want view the Security-Tab in folder 1 the following error occurs: <!-- Traceback (innermost last): File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 222, in publish_module File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 187, in publish File /usr/share/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 171, in publish File /usr/lib/python1.5/site-packages/ZPublisher/mapply.py, line 160, in mapply (Object: manage_access) File /usr/lib/python1.5/site-packages/ZPublisher/Publish.py, line 112, in call_object (Object: manage_access) File /usr/share/zope/lib/python/AccessControl/Role.py, line 257, in manage_access (Object: Traversable) File /usr/share/zope/lib/python/App/special_dtml.py, line 120, in __call__ (Object: access) File /usr/share/zope_2.2/Zope-2.2.0-src/lib/python/Products/ZDebug/DTMLLocator.py, line 103, in __call__ (Object: access) File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: access) File /usr/share/zope_2.2/Zope-2.2.0-src/lib/python/Products/ZDebug/DTMLDebug.py, line 288, in debug_render_blocks File /usr/share/zope_2.2/Zope-2.2.0-src/lib/python/Products/ZDebug/DTMLDebug.py, line 286, in debug_render_blocks File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_With.py, line 146, in render (Object: _.namespace(valid_roles=valid_roles())) File /usr/share/zope_2.2/Zope-2.2.0-src/lib/python/Products/ZDebug/DTMLDebug.py, line 288, in debug_render_blocks File /usr/share/zope_2.2/Zope-2.2.0-src/lib/python/Products/ZDebug/DTMLDebug.py, line 221, in debugException (Object: renderwob) File /usr/share/zope_2.2/Zope-2.2.0-src/lib/python/Products/ZDebug/DTMLDebug.py, line 286, in debug_render_blocks File /usr/lib/python1.5/site-packages/DocumentTemplate/DT_In.py, line 630, in renderwob (Object: permission_settings) File /usr/share/zope/lib/python/AccessControl/Role.py, line 183, in permission_settings (Object: Traversable) File /usr/share/zope/lib/python/AccessControl/Role.py, line 178, in <lambda> AttributeError: (see above) --> can anyone help or explain me what happens thanks as
