9 years ago this ticket is quite old. did you manage to fix the issue? would be great if you shared your experience with others.
when updating s&d I often had a ComponentLookupError for the ISalt which might be related, although your error looks quite different:
A fix for this problem is documented in the s&d mailing list:
Start the debug instance and use PDBDebugMode to access the portal object (http://nohost/plone/pdb) and perform the following steps::
portal = self.context.portal_url.getPortalObject()
import collective.dancing
collective.dancing.channel.tool_added(portal.portal_newsletters,None)
import transaction
transaction.commit()
Hi, We're looking at upgrading a plone site that uses singing and dancing, and came across an issue whereby the buildout works but the instance crashes due to the following:
TypeError: ('object.new(Salt) is not safe, use persistent.Persistent.new()', <function _reconstructor at 0xb753d1b4>, (<class 'collective.dancing.channel.Salt'>, <type 'object'>, None)) 2014-05-23 13:04:19 ERROR ZODB.Connection Couldn't load state for 0x1a78 Traceback (most recent call last): File "/home/zope/site/eggs/ZODB3-3.10.5-py2.6-linux-i686.egg/ZODB/Connection.py", line 860, in setstate self._setstate(obj) File "/home/zope/site/eggs/ZODB3-3.10.5-py2.6-linux-i686.egg/ZODB/Connection.py", line 914, in _setstate self._reader.setGhostState(obj, p) File "/home/zope/site/eggs/ZODB3-3.10.5-py2.6-linux-i686.egg/ZODB/serialize.py", line 612, in setGhostState state = self.getState(pickle) File "/home/zope/site/eggs/ZODB3-3.10.5-py2.6-linux-i686.egg/ZODB/serialize.py", line 605, in getState return unpickler.load() File "/home/dev/buildout.python/python-2.6/lib/python2.6/copy_reg.py", line 48, in _reconstructor obj = object.new(cls) TypeError: ('object.new(Salt) is not safe, use Persistence.Persistent.new()', <function _reconstructor at 0xb753d1b4>, (<class 'collective.dancing.channel.Salt'>, <type 'object'>, None))
Can anyone recommend the best approach here? I'm thinking i'll have to export the content whilst running under 4.1.5, delete it from 4.3, then re-import? Thanks!
