use base or use parent?

[Dermot-2]

Hi,

I have a controller with

use parent 'Catalyst::Controller';

I can't find any info on 'parent'

I want to use FormBuilder and tried to use it like so

use parent 'Catalyst::Controller';
use base qw(Catalyst::Controller::FormBuilder);

FormBuilder sends debug messages to the server but my controller can't
locate the method:

[error] Caught exception in MyApp::Controller::Submissions->edit
"Can't locate object method "form" via package "MyApp" at line 47


sub edit : Local Form {
  my ($self, $c, $id) = @_;
  my $sub = $c->model('MyAppDB::Submissions')->find({id => $id});
  if ($c->form->submitted && $c->form->validate) {
        $sub->name($c->form->field('name'));
        $c->stash->{message} = 'Updated'.$sub->name;
        $c->forward('list');
  }
...snip

I think this is a problem of inheritance. Can any one advise?
Thanx,
Dp.

Use $self->formbuilder, not $c->form.  You might enjoy this page:

Anyway, I'm not sure why you would think that "use base
'Catalyst::Controller::FormBuilder'" in a controller would add methods
to $c, so I won't even ask.

Ouch. You've discovered my source.
