I've got a problem with AdaptableStorage. If I set up a folder with AdaptableStorage I can add a CMF site to it but not a Plone site. I get: Traceback (innermost last): Module ZPublisher.Publish, line 102, in publish Module Zope, line 188, in commit Module ZODB.Transaction, line 222, in commit Module ZODB.Transaction, line 195, in commit Module ZODB.Transaction, line 256, in _commit_objects Module Products.AdaptableStorage.zodb.ASConnection, line 247, in commit Module Products.AdaptableStorage.mapper.ObjectSerializer, line 87, in serialize Module Products.AdaptableStorage.zodb.RemainingState, line 107, in serialize RuntimeError: Unable to pickle the '_catalog' attribute, <Catalog instance at 99526d0>, of <CatalogTool instance at 995d650> at ('/fs/test2/portal_catalog',). Cannot pickle <extension class Acquisition.ImplicitAcquirerWrapper at 40233ca0> objects. I don't understand how a portal_catalog won't pickle with AdaptableStorage but will with the ZODB. Thanks!
