I was wondering if anyone could offer advice or an example (if handy) for
creating a DateWidget using the form2 package.  I'm thinking of something
along the lines of 3 SingleSelectWidgets grouped together (each representing
day, month, and year).  This lead me to investigate the WidgetList, but I'm
having a hard time understanding how use it.  In the form I tried adding one
as follows:

        self.add(WidgetList, 'bday', element_type=SingleSelectWidget,
                 element_name="day",
                 value=None, title='Birthday:',
                 options=[ "1", "2" ],
                 required=True)

which raises a ValueError:
ValueError: a non-empty list of 'options' is required

That was my best guess after poking through the code, but I'm sure I'm over
looking something.  Any thoughts?  Thanks in advance,

-Charles.
