I'm not an expert at these kind of things but 3 tips: * Don't bother with trying to run off the old Data.fs until you get your product working in the new Zope.
* Inspect your code and what kind of objects (and most likely more importantly) and attributes you're attaching to classes that are persistent. I've forgotten my case now but I remember that I had a problem when I was trying to set an attribute that turned out to be a uncalled class method of another class. * Get familiar with this: 'import pdb; pdb.set_trace()' On 19/03/2008, Mark Hellewell <[EMAIL PROTECTED]> wrote: > 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 > _______________________________________________ > Zope maillist - Zope@zope.org > http://mail.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://mail.zope.org/mailman/listinfo/zope-announce > http://mail.zope.org/mailman/listinfo/zope-dev ) > -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
