I use special "handler" to process form actions. We need Page Template file 
(index.pt) and Python Script (formHandler).

index.pt looks like this:

<html>
...

<tal:block replace="structure here/formHandler" />

formHandler at least contains handlers for each action:

...

if hasattr(request, 'action1'):
     do_something()

elif hasattr(request, 'action2'):
     call_other_script()

It's basis. I made very complex things around this: set/change request 
variables, validation, error messages, etc.
