Storing objects in dictionary

[Feghhi, Jalil]

I get an error storing an object in a dictionary. The dictionary and the object are both provided by mod_python. One is the session object (which is just a dictionary) and one is a FieldStorage object (I think it is a class but displays as a dictionary). My question is what is the requirement for an object to be able to store it in a dictionary? I am sure there is documentaion somewehre but I couldn't find it.

Regards,
