carl, thank

found the problem, I always called

$form->model->default_values

regardless if submitted or not, putting that in the not submitted part of the else made it work - thanks!

btw, I have 5 of those selects in the form, which need all to be present (which works now) AND should be unique. 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:

$form->get_constraint('email')->force_errors(1);
$form->process;
$form->form_error_message('not saved');
$form->force_error_message(1);

how would I select the correct constraint (get_constraint) within the repeatable block? or is there an easier way to have unique select values within the repeatable block without evaling the db call?

thanks
