I was able to reproduce this problem with copied ActionInfo objects. A fix for the copy method is on the CMF-1_5-branch. Hope that fixes your issue as well.
Thank you very much! The bug is fixed. Christian _______________________________________________ Zope-CMF maillist - Zope-CMF@lists.zope.org http://mail.zope.org/mailman/listinfo/zope-cmf See http://collector.zope.org/CMF for bug reports and feature requests
