I tried it, but it didn't work (yet)...  For using something like
'self.get_widget_value()' on a button, I think that I would need a
'request' as an argument, right?  (And then I would expect to use
'get_submit_value()' to access the value of the button pressed).

Otherwise, it will always have the value given on the construction; if
I create it with
        self.add_submit_button("add", "Add a new name")
then
        self.get_widget_value("add")
will always lead to "Add a new name" (at least inside '__init__()')

I still did not figure out how to used the ListWidget...  Could you
please send me an example?

Thanks,
