[Catalyst] Any recommendations for multiple forms in catalyst (have been using HTML::FormFu)?

[kakimoto at tpg.com.au]

Hello Carl,
  Thanks for that. Sounds good but a few questions to ask.

1) I have read through the Actions section in
http://search.cpan.org/~zarquon/Catalyst-Manual-5.7012/lib/Catalyst/Manual/Intro.pod#Actions
and yet I couldn't really find anything that describes what the third
argument in 
"sub form2 : Path : FormMethod('_build_form2')" means. In that, I meant,
"FormMethod('_build_form2')".

2) From sub build_form_2, you mentioned that 
>     # return hash-ref based on $c->req->params->{loan_type}
>     # automatically gets passed to $form->populate

Is it possible for me to: 
 a) load_config_file() of a certain file which I define (for example,
"home_loans.yml")
 b) and return  the form object that has just runned load_config_file
(as per the step above)?


Any sites you could point me to read in reference to the first question
would be great.

 Thanks!

kakimoto
