Newbie Catalyst dispatch question

[mobiusinversion]

Hi Monks,
I have a question regarding basic Catalyst dispatching. Lets say I have a public url like this:

/app/reporting/42

Which displays reports about the account with account_id 42. I tried this:

package MyApp::Controller::App::Reporting;

use Moose;
use namespace::autoclean;

BEGIN {
    extends 'Catalyst::Controller';
}

sub reporting :Chained('chained_index') PathPart('reporting') Args(1) 
+{
    my( $self, $c, $account_id ) = @_;
    $c->log->debug( "Generating report for account $account_if" );
}

But when I fire up my Catalyst servers I see this:

[debug] Unattached Chained actions:

.-------------------------------------+-------------------------------
+-------.
| Private                             | Missing parent                
+       |
+-------------------------------------+-------------------------------
+-------+
| /app/reporting/reporting            | /app/reporting/chained_index  
+       |
'-------------------------------------+-------------------------------
+-------'

My question is how do I go about creating a method that will handle requests to urls of the form /app/reporting/id, In general I am trying to wrap my head around Catlayst controllers, in particular, how to structure controller for paths. Eventually (next week) I'll need to do create controllers to handle requests like:

/app/reporting/42/product_group/foo/product/bar

that will need to report on account id 42, product group id 'foo' and product id 'bar'. How would I do this? Thanks in advance for the help monks. Any help in the right direction would be awesome. I'm reading the docs but still not getting it.

The docs are much better than they used to be but they still require too much caffeine to absorb. Chained Examples.

package MyApp::Controller::App::Reporting;
use Moose;
use namespace::autoclean;
BEGIN { extends "Catalyst::Controller" }

sub by_id :Chained("/") :PathPart("reporting") :CaptureArgs(1) {
    my( $self, $c, $id ) = @_;
    $c->stash( ohaid => $id );
}

sub reporting :Chained("by_id") PathPart("") Args(0) {
    my( $self, $c ) = @_;
    $c->response->body("OHAI " . $c->stash->{ohaid});
}

__PACKAGE__->meta->make_immutable;
