[Zope-dev] Recursively adding ZClasses (continued)

[Rik Hoekstra]

Thanks for replying Kevin, but it won't work ;-( I tried it ALL, and it
_will_not_work_. The nested ZClasses will apparently solve it (I used it
elsewhere), but it will get you into trouble in other situations - if
you want to add an instance of the nested zclass to an existing instance
of that same nested zclass. I had to change my product before because of
that.

No matter if you use ZClass_add directly or in  dtml-with. No matter if
you close the first dtml-with and open another. No matter if you
redirect to get out of namespace problems (that will _really_ give
strange errors). Believe me, it was a _very_ frustrating experience (and
I really wanted to refrain from ranting -just couldn't help myself)

thanks again for replying
