Regarding storing the class in the session is not a problem that work fine
for me(need to be careful some things can't be pickel), the problem is
re-write it at each call,
I already try something similar to
order = session.order or Order()
I did,
if not isinstance("session.order",Order):
session.order=Order()
that didnt work session.order look always like empty to the validation,
since a python module just get imported once, if I move the class out of the
models in the web2py and put it in a file and imported something
from Order import *
Maybe thats work.
Any other ideas how to do this?
BTW: Thanks for the help if in the mean while i figure this one out I will
post it here.
