I have a form(1) widget:

    widgets['venue'] = StringWidget('venue', value='', size=18)

which is giving me fits when I evaluate it:

    template.set_venue(widgets['venue'].parse(request))

because although I explicitly set the value to the empty string in my
constructor, the value is set to None by Widget.Parse.  (This logic seems to
hold in form(2) as well, so converting doesn't look like it will help.)
What's the logic behind that sort of move?  Can I thwart it in a reasonable
way or do I have to always extract values like so:

    widgets['venue'].parse(request) or ""

?

Thanks,
