You cannot simply pass a ZOPE object in a form like that.
You can handle fairly complex structures (lists and dictionaries
with int, float, string in them) but whole objects would
need to be pickled and then open a huge security hole
(Whatever is in the client can and will be faked)

So best option I see is to not pass the object but rather
pass the reference to the object. You can resolve
it via restrictedTraverse('/path/from/form')

Btw. avoid much code in the Template. Its a maintenance
headache. You can do it esily in a python script and 
call this from template.
