[Catalyst] More than one form per page with C::C::FormBuilder?

Hey all!

I am trying to figure out the most elegant way to build/include multiple 
forms in one page using Catalyst::Controller::FormBuilder.

Right now I am doing it as follows...

In my controller:

   sub foo : Local Form
     my ( $self, $c ) = @_;

     # Form that actually belongs to "foo"
     my $form = $self->formbuilder;

     # Form for the search bar, belongs to "foo_search"
     my $search_form = $c->forward('foo_search');

   sub foo_search : Local Form
     my ( $self, $c ) = @_;

     # Form that belongs to "foo_search"
     my $form = $self->formbuilder;

     # Return the search form
     return $form;

In the "foo.tt" template:

   <!-- Should be the "foo_search" form -->
   [% INCLUDE foo_search.tt %]

   <!-- Should render the "foo" form -->
   [% FormBuilder.render %]

In the foo_search.tt template:

   <!-- Should render the "foo_search" form -->
   [% FormBuilder.render %]

What I end up with when viewing the "foo" action page is two 
"foo_search" forms.  I understand why this happening, from an internals 
standpoint, but I am not sure how to get around it without ugly hacking. 
  I would like to be able to keep the niceness of the "Form" pragma in 
the controller and all the cool things that go along with it.

Has anyone found a good way to do this?  What about if I wanted to build 
two different forms from within one page directly in the action (not 
using forwards)?

Is the general rule of thumb to only use the "Form" pragma if there will 
only be one form, and use FormBuilder directly (so I can choose a unique 
variable namespace for each) if there will be multiple?
