[Zope-dev] Problems with RackMountable

[Itamar Shtull-Trauring]

I'm adding some RackMountable objects (subclassed from RackMountable and
SimpleItem.Item) and when I try to access them via URL I get an
AttributeError like they don't have attribute __of__:

               Traceback (innermost last):
                 File /hd1/zope/lib/python/ZPublisher/Publish.py, line 214,
in publish_module
                 File /hd1/zope/lib/python/ZPublisher/Publish.py, line 179,

                 File /hd1/zope/lib/python/Zope/__init__.py, line 202, in

515, in __get_attr__
                   (Object: cheese4)
               AttributeError: __of__

What am I doing wrong here?
