Quite possible that you have a form with something like this:
<input name="user.age:record" value="50" />
<input name="user.name:record" value="Dee" />
In python, if you do this::
def saveUser(self, user, REQUEST):
print user # will print {'age':'50', 'name':'Dee'}
REQUEST.SESSION.set('user_data', user) # will fail!
So you have to do this::
def saveUser(self, user, REQUEST):
user = dict(user)
print user # will print {'age':'50', 'name':'Dee'}
REQUEST.SESSION.set('user_data', user) # will work!

According to the zope book it should be possible to store dicts in session.
When I try to assign a dictionary to a ordinary zope 2 session, with
lists there is no problem. why?:
requestlist = {}
for i in self.request.form:
key = i
value = self.request.form[i]
requestlist[i] = self.request.form[i]
sess = self.context.REQUEST.SESSION
sess['pr_reqlist'] = requestlist
I get the following error:
