It's a powerful feature but it can be hard to understand what's going

How are you reassigning the values?  The main trick to understanding
OptionSelectWidget is to realize that widgets only use the supplied
value when the form is initially rendered.  If the form is submitted
then the values for widgets come from the request (if there is a value
for that widget in the request).

Look at HiddenWidget.set_current_value() for an example of how to set
the value and override what is in the request.  It would be nice if
there was method that worked on all widgets.  Maybe we could add a
"force" keyword to set_value.

In any case, OptionSelectWidget is tricky.
