I just realized that if the above was the case, you probably wouldn't
be getting the NoneType error, but the original list with one element.
Did you check your session contents to make sure the data was in
actually in there? If the new item was there in the session, perhaps
it was your if statement? Did you try
request.session.get('questionlist') instead of if 'questionlist' in
request.session. I would think either would work, but that is worth a
shot as well.
