Hello all,

I get something back froma ZCatalog (  results = myZCatalog({'myAttr': 
myValue})    )

Then I try to put results in session, like this:

...Request.Session['myResults'] = results

What I get back is an UnpickelableError message.

It seems that lists are not pickelable.

How can I store my results in a pickelable form? Can I?

I'd like tu put online my work, when done, so I'd like not using 
products (like RAM based session managers), since I don't know how many 
of them are supported by my host.

Please, please, please! Is there ANY possibility to put my objects in a 
pickelable set?

Less importantly: How can I know wether an object is pickelable or not? 
How can I know WHO my object inherits from?

In SmallTalk and Java I was used to class browsers and that did. How in 
Zope/python?

Are dictionaries pickelable? How do I distinguish a list from a 
dictionary?
Are there any kind of sets, other than lists and dictionaries?

Ok, I think I made clear what I'm at. Please help me

Thank you all.
Bye
