I think now that Catalyst::Controller::HTML::FormFu isn't first in the
inheritance list, its create_action() isn't being called.

If you change it to the following, you should find it works again:

 use parent qw/
           Catalyst::Controller::HTML::FormFu
           Catalyst::Controller::DBIC::Transaction
           /;

If any Cat dev could point me to a Cat controller that does the action
registering correctly, so I can fix C-C-HTML-FormFu, I'd very much
appreciate it.
