Some days I need help doing anything! :-)

No I meant that, for example, when I go back to an earlier page, I 
can update a given field but the original data (defined in the value 
attribute of the tag) is what sticks. The new data is ignored.

After a good nights sleep, I found at least part of my problem. By 
loading my session data into the CGI object in my _get_session 
routine, I was overwriting the new form data before. That's the 
problem with using too much abstraction/indirection; you occasionally 
lose track of what is actually happening and in what order.

Now all I have to do is figure out why the ValidateRM plugin is not 
properly filling in my previous radio-buttons...

I'll check this out, thanks! In the meantime, I've added some logging 
statments using the LogDispatch plugin to get a better view of the 
data flow through my app.

Sergej
