Nobody dared to answer? Well, I am not in big trouble here - I have
previous backup; I can import it and will redo all changes.
But I think I found a bug or undocumented misfeature in Zope External
Methods. The problem is in default parameter (render=default_render). By
some reason Zope stores (pickles?) it in wrong way, so later it cannot be
imported. I'll remove this argument (or replace it with render=None) and I
am sure the problem will gone away, and I can export and reimport it
safely.
Oleg.
