Checkboxgroup doesn't override process(), so if _Group::process()
isn't being called, it's likely you're not calling $form->process()
Are you using Catalyst-Controller-HTML-FormFu ?

It should be "name: areas", to match the name of the many_to_many relationship

__PACKAGE__->many_to_many(areas => 'area_rel', 'area_id',);
is wrong, the 3rd argument 'area_id' should be the name of the
relationship in the link table that points to the area table.
