[Catalyst] another newbie chaining question

[John Napiorkowski]

Some debug info on this.

In my action I have:

my @actions = @{$c->action->chain};
	
my $previous = $#actions-1;
my $previous_action = $actions[$previous];
	
$c->log->dumper($previous_action);

$c->log->dumper($c->uri_for($previous_action,
$c->request->captures));

And this is what I get from the debug console:

[debug] $VAR1 = bless( {
                 'attributes' => {
                                   'CaptureArgs' => [
                                                     
0
                                                    ],
                                   'Chained' => [
                                                  '/'
                                                ],
                                   'PartPath' => [
                                                  
'templates'
                                                 ]
                                 },
                 'class' =>
'services::Controller::templates',
                 'code' => sub { "DUMMY" },
                 'name' => 'templates',
                 'namespace' => 'templates',
                 'reverse' => 'templates/templates'
               }, 'Catalyst::Action' );

[debug] $VAR1 = undef;

So it appears I got the right action object but I
can't seem to get the URI for it.  Does this have
something to do with that fact it may not have fully
dispatched yet?
