I'm trying to publish my own module with ZServer (from Zope 2.2.0). I get the following traceback: Traceback (most recent call last): File "z2.py", line 673, in ? from AccessControl.User import super File "/home/beluga/skip/src/Zope-2.2.0-src/lib/python/AccessControl/User.py", line 89, in ? import Globals, socket, regex, SpecialUsers File "/home/beluga/skip/src/Zope-2.2.0-src/lib/python/Globals.py", line 90, in ? import Acquisition, ComputedAttribute, App.PersistentExtra, os File "/home/beluga/skip/src/Zope-2.2.0-src/lib/python/App/PersistentExtra.py", line 87, in ? from Persistence import Persistent ImportError: cannot import name Persistent When I look at lib/python/Persistence.py, all I see is a copyright notice and the following short doc string: """Provide access to Persistent and PersistentMapping This avoids dependency on the database package name. """ I can't find a definition of an object named Persistent (probably ought to be a class or ExtensionClass, based upon the usage I saw) anywhere in the Zope 2.2.0 tree.
