you guys are very picky i just wrote an easy example the original
function was more complicated and cause an error that was very
cryptic, btw something that should be improved too
i tried to save the not existend var (form.vars.id) into a session
variable which caused the following error
session.mid = form.vars.id
Error traceback
Traceback (most recent call last):
File "/home//web2py/gluon/main.py", line 507, in wsgibase
session._try_store_on_disk(request, response)
File "/home//web2py/gluon/globals.py", line 375, in
_try_store_on_disk
cPickle.dump(dict(self), response.session_file)
PicklingError: Value returned by <function Reference_pickler at
0x98b225c> must be string or tuple
In file: Framework
no hint to what the actual line is that caused the problem, had to
debug old school, deleting large to small blocks of code to narrow it
down
