Hi Markus,

I think you've been confused by the documentation which gives an
example of FormMethod('load_form') as a way to call a method in your
own controller, to return a form.
If that's all you want to do, you don't need to sub class, just make
sure that you use FormMethod() instead of FormConfig(), and that the
load_form() method is in your controller class.
The reason it's not currently working, is there's no load_form()
method anywhere in the FormFu controller code, so nothing's calling
it.

An example of what I think you should be doing:

package Superclix::Controller::Partnerprogramm;
use strict;
use warnings;
use parent 'Catalyst::Controller';

sub load_form {
    my ($self, $c) = @_;
    # returns a HTML::FormFu object
    # can get an empty form to start with using $c->form;
}

sub neu : Local : FormMethod('load_form') {
    my ($self, $c) = @_;

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

Cheers,
Carl
