Ah, that way! I was thinking more in object oriented ways. The field
has a value, so I should be asking something of that field. Instead,
the form returns the values of the fields.

I might make sense from an implementation viewpoint, especially if you
want to store the validated results in the REQUEST. That can probably
only be done from the form. From a pythonic viewpoint - to me - it was
a bit unexpected. For display of the fields in a form, you call
field.render_view() or so, but if you want the value you can't do
field.value() but have to ask the form for it. Huh?

I'll keep it in mind for the next time I look at ploneformmailer. At
the moment it does what we need it too. But I expect some more coding
in a few weeks - a good time to make it more well-behaved at the same
time :-)
