Yes. (well, it would be obj.portal_type of course) An interface would be better though, as that makes sure that your subscriber only gets called when one of your announcements is being transitioned. So that would be something like this in your configure.zcml: ========================================== <configure xmlns="http://namespaces.zope.org/zope";> <subscriber for=".interfaces.IAnnouncement Products.DCWorkflow.interfaces.IAfterTransitionEvent" handler=".subscribers.emailListListener" /> </configure> ========================================== In interfaces.py: ========================================== from zope.interface import Interface class IAnnouncement(Interface): pass ========================================== In announcement.py (or wherever you define the Announcement class): ========================================== from zope.interface import implements from interfaces import IAnnouncement class Announcement(...): ... implements(IAnnouncement) ... ========================================== -- Maurits van Rees | http://maurits.vanrees.org/ Work | http://zestsoftware.nl/ "This is your day, don't let them take it away."
