[Catalyst] Nonsensical Problem with DBIx ResultSet

[Kyle Hall]

Hello all,
  I'm the developer of a FOSS kiosk management system, Libki. I'm in the
early stages of a complete rewrite using Catalyst for the web-based
administration interface. This is my first time using Catalyst, but I'm very
excited by the possibilities! I'm having a very strange issue with my
resultsets. For example, I have three tables, a users table, a clients
table, and a sessions table that connects the user to a client.

I grab my users from the database, with any session/client data if the user
is currently logged in to a client kiosk. I am prefetching the session and
client table data.

my $user_rs =3D $c->model('DB::User')->search( {}, { prefetch =3D> { sessio=
n =3D>
'client' } } );

Now I want to loop through it.

    my $row =3D 0;
    my @row_data;

    while ( my $user =3D $user_rs->next() ) {
        my $user_id =3D $user->id;

        warn $user->session->client->clientname;

        my $single_row =3D {
            cell =3D> [
                $user->id,
                $user->username,
                $user->minutes,
                $user->status,
                $user->is_troublemaker,
                $user->session->client->clientname;
            ]
        };
        push( @row_data, $single_row );
    }


Now, if I try to access any of the other tables, I get an error:
[error] Caught exception in LibkiServer::Controller::Admin::REST->users
"Can't call method "client" on an undefined value at
/home/libki/LibkiServer/script/../lib/LibkiServer/Controller/Admin/REST.pm
line 40."

I don't know why I get this error, but the really crazy part is *the warn
still works*:
Client Name: testclient1 at
/home/libki/LibkiServer/script/../lib/LibkiServer/Controller/Admin/REST.pm
line 40.

If anyone can help me out, I'd be eternally grateful.

Thanks,
Kyle
