[Catalyst] another newbie chaining question

[John Napiorkowski]

After a little more digging I discovered that
$c->action when inside a chained action is actually an
ActionChain object.  This is like an object that wraps
each action in the chain up to this point.  It has a
method called ->chain which returns an array ref.  So
I though I could get the previous action thusly:

my @actions = @{$c->action->chain};

my $previous = $#action-1;
my $previous_action = $actions($previous);

However I find this doesn't quite work right.  Does
anyone know if I am on the correct track?

Thanks!

John
