[Catalyst] Controller::ActionRole and Controller::FormFu

[Peter Shangov]

Hi Tobias,

You cannot use Controller::FormFu together with Controller::ActionRole - both inherit from Catalyst::Controller and attempting to inherit from both of them creates a mess. 

C::FF is just sugar over ordinary HTML::FormFu syntax. The C::FF docs explain exactly what 'FormConfig' and the other attributes do, so you should use that extended syntax instead, i.e.:

sub settings :
        Chained('base')
        Args(0)
        Does(ACL)
        RequiresRole('some-role')       
        ACLDetachTo('/permission_denied')
{
    my ($self, $c) = @_;
    my $form = HTML::FormFu->new;
    $form->load_config_filestem('root/forms/settings');
    ...
}
 
Ideally C::FF will be implemented as an action role in the future, but this has not been done yet.

Cheers,
