Ecco la mia soluzione funzionante basata su weblion
# Dump this in a Custom Script Adapter.
# Available parameters:
# fields = HTTP request form fields as key value pairs
# request = The current HTTP request.
# Access fields by request.form["myfieldname"]
# ploneformgen = PloneFormGen object
#
# Return value is not processed -- unless you
# return a dictionary with contents. That's regarded
# as an error and will stop processing of actions
# and return the user to the form. Error dictionaries
# should be of the form {'field_id':'Error message'}
# Do some setup:
upload_folder = context.circolari['allegati']
## Save the answer to the question of ID "thingy":
uploaded_file = fields['allegato_file']
# Prepend the user ID; append the right file extension:
upload_id = uploaded_file.filename
# If the file isn't already there, create it:
if upload_id not in upload_folder.objectIds():
upload_folder.invokeFactory('File', id=upload_id)
# Dump the uploaded content into it:
file = upload_folder[upload_id]
file.setFile(uploaded_file.read(), filename=upload_id,
content_type=uploaded_file.headers['Content-Type'])
