[Catalyst] Class data in a Moose::Role plugin

[Bill Moseley]

I also tried with Catalyst::ClassData.  Must be missing something.

All modules up to date.  On Perl 5.10.0.

$ catalyst.pl MyApp



$ cat lib/Catalyst/Plugin/Role.pm
package Catalyst::Plugin::Role;
use Moose::Role;
use MooseX::ClassAttribute;

class_has 'Cache' =>
        ( is      => 'rw',
          isa     => 'HashRef',
          default => sub { {} },
        );
1;

$ script/myapp_server.pl

With Catalyst::ClassData:

moseley at bumby2:~/MyApp$ cat lib/Catalyst/Plugin/Role.pm
package Catalyst::Plugin::Role;
use Moose::Role;
use Catalyst::ClassData;

__PACKAGE__->mk_classdata( 'foo' );
1;

moseley at bumby2:~/MyApp$ script/myapp_test.pl /
