Re: [Zope3-Users] Vocabulary with objects and persistence problem
Solved! Thanks to Thierry Florac for pointing in the right direction: Thierry Florac wrote: Well, not absolutely sure but the problem may come that "source" attribute is automatically defined as a 'simple' list (see introspector to be sure), and not as a persistent one ; as a list is a mutable object, changing one of it's attributes or adding/removing an item doesn't flag the list as modified "from the persistent object point of view", so it isn't stored into the ZODB when the transaction is committed. So you may have two solutions to handle this in the "removeSource" method : 1. sources = self.source sources.remove(source) self.source = sources 2. self.source.remove(source) self._p_changed = True ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] Vocabulary with objects and persistence problem
I've checked everything. There are no error messages and transaction seems to comit fine. Does a way exist to trace a transaction?

Are you sure the transaction commit isn't failing in some way? -- Christopher Warner Manager, Content Management Systems New York Media | 75 Varick St, 4th Fl New York, NY 10013 phone: 212.508.0542 cell: 646.334.6780 On 4/3/09 11:08 AM, "Nylan" wrote: > Hello, > I'm having some weird problem using objects references in a vocabulary. > > Following situation: > Container A - Objects type X > Container B - objects type Y with zope.schema.Choice based on vocabulary of > objects X > > After deleting object X1 in container A and removing > manually(ObjectRemovedEvent > iterating container B, removing reference and transaction.commit) the > reference > in object Y, X1 doesn't show up and everything looks fine. > > After restarting zope i get a LookupError.
