[Catalyst] Can't seem to use forward or detach. Any special requirements?

[kakimoto at tpg.com.au]

Hello, Oliver,

 Good morning.
 Referring to
http://kobesearch.cpan.org/htdocs/Catalyst-Runtime/Catalyst.html#c_gt_detach_class_method_arguments,
under "$c->detach()",
it says that detach is the same as forward, but doesn't return to the
previous action when processing is finished. 

 Comments?

thank you
