In the end, the hack that worked involved calling render again, from
process -- if the OptionSelectWidget onchange() event happens,
submit_button is "", so a re-render et voila.

Not sure if that's working as designed or intended but it works. In my case
I needed to re-render the same fields but with different values, one of
which is the language value from the OptionSelectWidget.

     def process (self, request):
         # check so see if we are here as a result of the OptionSelect widget
         # submit will be "" if it was used as opposed to the "update"
         # "delete" or "add" buttons being selected

         submit = self.get_submit_button(request)
         if request.form and submit == "":
             return self.render(request, 'details')   #hard coded hack for now

         form_data = ParlezForm.process(self, request)
         # snip various tests
         return form_data

It took a bit of churning before I realized that widget values were only
set for the initial render. Playing with widgets outside of form made it a
bit easier to understand what I was missing.

Thanks for the tip.
