Hello Iap,

>> This external method helps a zclass to change
the old reference of its base class (an instance of ZClass)
to the new one  in "new" ZODB.

Thank you very much.
I will try it when I will have a little bit of time.
(and in particular profit to update to the version of Zope
in which you can define DTML-python methods).

>> "Zclasses are not robust solutions they mostly seem designed for trivial
solutions by largely non programmers."

If we except this BUG and difficulty with DTML Zope to change the
inheritance
hierarchy, and given that now you can define Python method directly from
with the Zope environment, Zope could have been a very good (flexible)
environment
to design complex applications.
I personaly believe that there should exist some way to have very flexible
environments to design complex application. Zope has provided us with a very
interesting approach (in particular how to combine object orientation and
persistance in a system in a very straighforeward way), but not yet enough
unfortunatly :-).

Thanks again for your suggestion.
