Is there a possibility to check this thing during startup, when zcml is parsed? That would save time finding out what the real problem is. It's a feature, not a bug. :) Martin -- Acquisition is a jealous mistress ___ Zope3-dev mailing list Zope3-dev@zope.org Unsub: http://mail.zope.org/mailman/options/zope3-dev/archive%40mail-archive.com
