Hi Carl,
I can't make it work. The  Checkboxgroup is not being populated.
Element/_Group::process is not being called at all.

This is what I have in the config file:

          - type: Checkboxgroup
            name: area_rel
            db:
              model: DBIC::Area
              label_col: name
            constraints: [ AutoSet ]

The rels in DBIC::Campanha model:

__PACKAGE__->has_many(
    area_rel =3D> 'SMS::Schema::Result::AreaCampanha', 'campanha_id',
);
__PACKAGE__->many_to_many(areas =3D> 'area_rel', 'area_id',);

# in my app:

$form->defaults_from_model( $campanha_row );

If I change the rel in the config to "name: areas" instead of "name:
area_rel" I got this error:

[error] DBIx::Class::Relationship::ManyToMany::__ANON__(): search_related:
result source 'AreaCampanha' has no such relationship area_id at
/Library/Perl/5.8.6/HTML/FormFu/Model/DBIC.pm line 186


Do you have any idea what am I doing wrong?

Thanks
