Jim added a comment in >http://dev.zope.org/Wikis/DevSite/Proposals/IncludeEventsInCore saying >(unsurprisingly) that he'd rather use the Zope 3 event system. I fear that we also need to control the order in which subscribers are notified: Consider for example the notification about the creation of a object. Both the catalog service and the workflow service need to be notified. If the catalog service is notified first, the workflow service must renotify the catalog service to get the workflow variables indexed. -- Dieter ___ Zope-Dev maillist - [EMAIL PROTECTED] http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
[Zope-dev] getUserById
In User.py the method is defined as def getUserById(self, id, default=_marker): try: return self.getUser(id) except: if default is _marker: raise return default I am wondering whether anybody actually depends on the fact that getUser is supposed to raise an exception. I know of no user folder implementation that actually does that. Rather, I'd like to change it to the way it's done in LDAPUserFolder where the method looks (more or less) like: def getUserById(self, id, default=_marker): user = self.getUser(id) if user is None and default is not _marker: return default return user Any objections?
