Hi Asad ,

I was afraid of that ;-(. But let me spin around yet:

- Views:
    --- Editing/Creating business objects:
            ZPT's/DTML's with appropriate properties managing view 
concerns, genaralized  for a  category
           of possible (already standardised) business/zope objects 
(gaining from aquisition rules)
    --- Displaying Results: Pluggable Brains as subclass of above ones

- Model : 
    Perhaps Zope Products ???, handling business logic , I'm not sure if 
that would work, perhaps a so
    called workaround with.interfacing and so on.

- Controllers:
   really PhytonSricpts, I think so, or alternatively dtml-methods


So, why I'm asking:

I want to implement a standardized web application (at this time it's 
only a stupid
choose and buy like any other so called e-commerce/shopping cart system 
, but my
intention is to make it almost configurable in all three aspects (i know 
... but William S. wrote
#################
#And enterprises of great pith and moment
#With this regard their currents turn awry,
#And lose the name of action. - Soft you now!
#The fair Ophelia! Nymph, in thy orisons
#Be all my sins remember'd.
################  ;-))

Is that totally wrong?
or is that a so called acceptable (but not ideal) approach?

Thanks in Advance
Thomas  Adams
