-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 If you attempt to import a SquishDot site that was exported from an older version of Zope (in my case, Zope 2.6.4) into Zope 2.8.0, you get an exception raised in Products.ZCatalog.Catalog.py at line 106 because self has no _length attribute. In other sections of code in Catalog.py, there's this chunk of code present: ~ if not hasattr(self, '_length'): ~ self.migrate__len__() It seems that this chunk of code should also be inserted before the reference to self._length in the clear() method. I did so, and it solved my issue with importing SquishDot sites. This bug in Catalog.clear() is also in Zope 2.8.1. - - Stephen - -- Stephen Bartlett President, Bartlett Software, Inc. http://www.bartlettsoftware.biz/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFDAPIrR7d3GIt7UjgRAnHeAJ9N5mw/EfzCCwYThGnBfuUd2YpG1ACfYOes wCbRIJ/bvV6z+xt1QT9gV78= =Kir0 -----END PGP SIGNATURE-----
