Hi Jonas,

http://search.cpan.org/~cfranks/HTML-FormFu-0.02002/lib/HTML/FormFu/Model/DBIC.pm#many_to_many_selection

You don't need the Block for that:

    type: Checkboxgroup
    name: area_rel

If area_id is the PK, it'll pick that up automatically, otherwise you
can be explicit:

    db: { default_column: area_id }

And this isn't documented yet because it may change, but with the
catalyst controller you can populate the Checkboxgroup from the db
like so:

    type: Checkboxgroup
    name: area_rel
    db:
      model: MyModel
      label_col: area

See the source of Element/_Group::process() for more details.

Cheers,
Carl
