I can achieve this by making a unique constraint in the db and catch the error in an eval around $form->model->update. my problem: how can I force_error on the correct field? I can't seem to get the fields within the repeatable block. I normally do this like that:

found a way to make this work:

addedd

validator: 'Cat::UniqueCopmanyInDepots'

in my config, made

Cat/lib/HTML/FormFu/Validator/Cat/UniqueCopmanyInDepots.pm

as described in http://search.cpan.org/~cfranks/HTML-FormFu-0.06000/lib/HTML/FormFu/Validator.pm

very nice solution - thanks for that carl!
