I think this is actually a bug in Zope. I added some logging statements to UndoTool.py and found that the transactions list returned by portal.undoable_transactions() was empty for users not defined in the root acl_users.
I then googled for "zope 2.7 undo acl_users" and found this: http://www.zope.org/Collectors/Zope/1810 I applied the patch, and it seems to fix the problem I had. I wonder if this is a proper fix, or if there may be some unintended side-effects. I'm tempted to go with it, although instead of changing the Prefix.py file itself, I think I'll write a little monkey-patch to replace the __cmp__ method at runtime. --- Sam Brauer <[EMAIL PROTECTED]> wrote: > I've recently encountered a similar problem, and I'm > not using Plone.
