[Zope] HELP: CST and python scripts

[Chris McDonough]

Well.. file objects can be "stringified" for storage in the session
(if you've got the RAM, this is asking for abuse though):

for k, v in context.REQUEST.form.items():
    context.session_data_mgr.getSessionData()['k'] = str(v)

This will also stringify lists and ints and such in the form as
well, which may not be what you want.
