In your view you have only Administration model fields, no Credit
model fields (I assume from your example) - so the form helper don't
know where to place any invalid field information from the Credit
model.
Try either to use Credit model fields, or maybe change this:
[change]
$form->error('credits')
to
$form->error('Credit.credits');
[/change]
Haven't tried it, so no idea if it will work!
Enjoy,
