Hello,
I'm in the middle of trying to upgrade a Product written for Zope 2.7
so that it runs on Zope 2.10!
The product appears in the newer ZMI's list of available products but
whenever I try to add an object of the products type through the ZMI I
get the following error in the event.log and nothing is added to the
site:
Traceback (innermost last):
Module ZPublisher.Publish, line 125, in publish
Module Zope2.App.startup, line 238, in commit
Module transaction._manager, line 96, in commit
Module transaction._transaction, line 395, in commit
Module transaction._transaction, line 495, in _commitResources
Module ZODB.Connection, line 502, in commit
Module ZODB.Connection, line 1046, in savepoint
Module ZODB.Connection, line 555, in _commit
Module ZODB.Connection, line 582, in _store_objects
Module ZODB.serialize, line 407, in serialize
TypeError: Can't pickle objects in acquisition wrappers.
additionally, if I take a Data.fs from my Zope 2.7 instance and try
running with it in place on a 2.10 instance the various objects of the
product already created simply don't show up (no broken icon, nothing)
Running Zope 2.10.5 and Python 2.4.4 and the Product in question was
written using CMF 1.4.2 (but now upgraded to CMF 1.6.4, I've made
several changes already to accomodate this upgrade)
I'd be grateful for any insight anyone might have or any hints at what
to do next!
Thanks,
Mark
