Hi Johannes,

After submission, you need to make sure you're adding all the dynamic
fields again, before calling process(), as FormFu will only allow
values that correspond to known fields.
I would normally handle this by writing a Plugin subclass that has a
process() method which adds the dynamic fields. This'll mean the
fields are present when FormConfig() calls $form->process().

Otherwise, you'll have to do something like this:

    sub edit : Chained('foo') : PathPart : Args(0) : FormConfig {
        my ( $self, $c ) = @_;

        my $form = $c->stash->{form};

        $self->_add_dynamic_fields( $form );

        $form->process();

        if ( $form->submitted_and_valid ) {
            # ...
        }

        return;
    }
