[Html-widget] Setting field values using query parameters

[Zbigniew Lukasiak]

You can process without query -
$widget->process()
And then set the values on the result object.

You might also look at mine, not yet released to CPAN,
HTML::Widget::DBIC - it's avalable at:
http://zby.aster.net.pl/HTML-Widget-DBIC-0.01.tar.gz or it is also a
part of the, released, Catalyst::Example::InstantCRUD.

It does a bit more than the DBIx::Class::HTMLWidget mentioned in
another letter as it can also set values from related tables even for
many-to-many relationship.  It also uses a config to separate the
visual things from the database layer.
