Yep, trying to access a newly instantiated empty zclass instance produces the same error. Looks like a bug. Email me if you want an exported version of my zclass to poke and prod at... Tres Seaver wrote:

Does the problem repeat in the "vanilla" version if you just create a new instance of your ZClass, instead of importing the old pickle? If so, it is definitely a "bug"; if not, it may be a "migration problem," with a fix like the one Brian posted for recursively "re-ownering" Zope.org.

If I take out manage_tabs from the offending ZClass index_html method, I can view index_html (but of course, I can't use the management stuff built in! making it rather useless), so that's where we're getting into trouble for sure.

I've tried starting out with a vanilla 2.2a1 Data.fs and importing all the zclasses and the relevent folders - no difference.

Anyone else seeing this? Is this worthy of the collector?
