I should clarify further. Your controller code:

  has 'form' => (
	isa	=>	'ml2::Forms::CreatorForm',
	is	=>	'rw',
	default	=>	sub { ml2::Forms::CreatorForm->new },
  );

is moreorless what the base controller does. So by having that 'has' 
declaration, you break it. Try taking the 'has' declaration out and see 
if that works.
