Here's a problem which bit me today. I'd delegated someone to manage a Yihaw directory. zope 2.2.2 source running on a sun. make a folder at the root (eg /foo) with an acl_user folder there define a new user in the foo acl_user folder (eg foobar) with manager/owner rights add a dtml method to view ZopeTime (eg <dtml-var ZopeTime> ) view it and see the current time. It's owned by a real manager and it works as expected. Now, close your browser down and authenticate as foobar and try to view the page. You'll get: Zope Error Zope has encountered an error while publishing this resource. Error Type: KeyError Error Value: ZopeTime Traceback (innermost last): File /udd/rerla/zope222/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /udd/rerla/zope222/lib/python/ZPublisher/Publish.py, line 187, in publish File /udd/rerla/zope222/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /udd/rerla/zope222/lib/python/ZPublisher/Publish.py, line 171, in publish File /udd/rerla/zope222/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: test) File /udd/rerla/zope222/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: test) File /udd/rerla/zope222/lib/python/OFS/DTMLMethod.py, line 172, in __call__ (Object: test) File /udd/rerla/zope222/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: test) KeyError: (see above) Note, it's not unauthorised - it's just not in the namespace. ZopeAttributionButton is defined in the same Application.py but it works fine. I even tried adding ZopeTime__roles__=None to no avail. What gives???
