[Zope] ZClass Confusion over object id

[Brian K. Holdsworth]

Thanks for the assistance Alexandre and Tres.  Your suggestion did the
trick.

It seems a little odd that this appeared in 2.0.1 and is still around in
2.1.2.  Does anyone know if a fix has been considered.  It seems it would be
pretty easy to just change the default 'add' method that gets created when a
ZClass is created and avoid this pitfall.  I'd volunteer to look at it, but
I'm sure a more elegant solution can be thought of by those more experienced
with Zope than I.

Best Regards,
Brian Holdsworth

Hi Brian,


This sounds like the DTML ZClass ID bug. Take a look at this doc:
