Hi, I am looking to migrate my existing zope 2.7 site to zope 2.12 and during initial testing I am getting this error when importing the zexp. Error Type: TypeError Error Value: ('argument list must be a tuple', <class 'Shared.DC.ZRDB.DA.SQL'>, None) Traceback (innermost last): Module ZPublisher.Publish, line 127, in publish Module ZPublisher.mapply, line 77, in mapply Module ZPublisher.Publish, line 47, in call_object Module OFS.ObjectManager, line 628, in manage_importObject Module OFS.ObjectManager, line 646, in _importObjectFromFile Module ZODB.ExportImport, line 92, in importFile Module transaction._transaction, line 253, in savepoint Module transaction._transaction, line 250, in savepoint Module transaction._transaction, line 647, in __init__ Module ZODB.Connection, line 1128, in savepoint Module ZODB.Connection, line 570, in _commit Module ZODB.ExportImport, line 176, in _importDuringCommit TypeError: ('argument list must be a tuple', <class 'Shared.DC.ZRDB.DA.SQL'>, None) As a test I removed the Z SQL Methods before exporting and this time it imported OK. Zope 2.7 server is OpenSuSE 10.3 with python 2.3, postgreSQL 8.2 and the DA is psycopg2 Zope 2.12 server is OpenSuSE 11.2 with python 2.6, postgreSQL 8.2 and DA is psycopg2 Any known issues and or work arounds?
