[Zope-dev] Can't edit CMF/Plone content if the creator is deleted

I don't know if this is a Zope, CMF, Plone or DCWorkflow issue, but I just got bitten by what appears to be a bug in someone's security handling. If you create some content as user A, then delete user A, no one can edit the content, or change it's ownership. I created a site as "manager" and created a bunch of content. Then I created the users that would actually be maintaining the content and deleted "manager" (It's far too easy to guess at). Suddenly, all updates started failing, and continued failing, untill I re-created the "manager" user. I have set the domain to 127.0.0.1 so the user can not log in, but I would really like to know if this is and intended security feature or a bug. Any input would be appreciated. Adrian...
