congrats ;-) .. you could look at CMFTypes which lowers the threshold
for developing products.  essentially you just define a schema and it
the classes and forms.

Attribute func_code I believe is returned when you run a python script
that isnt compiled or can not compile.  maybe look at this?  the traceback
in error_log didnt give you any more information?

if you click on a Pagetemplate and get the func_code exception...
some is vastly borked.  I have only gotten this from PythonScripts.
What version of Zope?
