I have a zclass I made with A4 and I am having problems getting it to work with B1. It inherits from objectmanager and I created another zclass in the methods view of the first zclass. So, after upgrading to B1 I can not longer ad instances of the child zclass to instances of the parent zclass. I get: Traceback (innermost last): File /opt/zope/lib/python/ZPublisher/Publish.py, line 256, in publish_module File /opt/zope/lib/python/ZPublisher/Publish.py, line 145, in publish File /opt/zope/lib/python/ZPublisher/BaseRequest.py, line 414, in traverse File /opt/zope/lib/python/AccessControl/User.py, line 373, in validate (Object: RoleManager) File /opt/zope/lib/python/ZPublisher/HTTPResponse.py, line 499, in notFoundError NotFound: (see above) I can also reproduce this with completey generic zclasses produced by Zope. I thought this had something to do with the new permissions stuff so I tried adding a permisions object to the product and then setting the permision property of the factory to it and then mapping 'view' in the constructor's security page to the new permision (per the what's changed in B1 page) and this didn't help. Is there something else I need to do - or have I done something wrong? Thanks, ^Roman
