Whoa there ... I didn't say anything you could disagree with. I just stated
facts. But I do agree that writing software in Zope is a problem for me too.
I would also like a flat text storage system, but I also see why it is
difficult considdering the design choices made in Zope.

I believe that my problems stems from the fact that code, content and
presentation is to strongly interwoven.

zClasses are nice and simple but difficult to edit, as it has to be done in
the browser. Or at least pasted into it. You also get yourself painted into
a corner pretty quickly.

Subclassing a Pyhton class as a base for a zClass is kind of nice. But
currently I am having problems using that method as it seems that "helper
classes" cannot be adressed from dtml methods in the zClass. (Se my acessing
parameters in a "helper class" posting).

Products are difficult to make, and all the tutorials are rather bad.
Business logic and presentation is mixed together. (Business logic should
not use any code or libraries from Zope at all.)

A nice way to work would be to make a Python class that is completely
independent of Zope. Test and debug it.

Then make a thin Zope wrapper that adds just enough functionality to make it
work in Zope, and so that it can be accessed nicely via dtml.

I am trying this approach currently, but it gets ugly real fast. It will
probably be nicer when I understand it fully. I Will post a How-to then.
