Capability, role and custom post type

Hy,

i just want code this:

Create a custom post type, give it a custom capability and let a custom role only access this.

So i created a new custom post type called “press” and gave the capability “press_review”, i added a role called “press dude” an gave him all access to only this kind of post type. But its not working…

add_action( 'init', 'create_my_post_types' );

function create_my_post_types() {
 register_post_type( 'press',
  array(
   'labels' => array(
    'name' => __( 'Press Reviews' ),
    'singular_name' => __( 'Press Review' ),
    'add_new' => __( 'Add New' ),
    'add_new_item' => __( 'Add New Press Review' ),
    'edit' => __( 'Edit' ),
    'edit_item' => __( 'Edit Press Review' ),
    'new_item' => __( 'New Reveiw' ),
    'view' => __( 'View Review' ),
    'view_item' => __( 'View Review' ),
    'search_items' => __( 'Search Press Review' ),
    'not_found' => __( 'No Press Reviews found' ),
    'not_found_in_trash' => __( 'No Press Review found in Trash' ),
    'parent' => __( 'Parent Press Review' ),
    'description' => __( 'A Press Review is a type of content where your Press Reviews are set up.'),

    /* Global control over capabilities. */
    'capability_type' => 'press_review',

    /* Specific control over capabilities. */
    'capabilities' => array(
    'edit_post' => 'edit_press_review',
    'edit_posts' => 'edit_press_reviews',
    'edit_others_posts' => 'edit_others_press_reviews',
    'publish_posts' => 'publish_press_reviews',
    'read_post' => 'read_press_review',
    'read_private_posts' => 'read_private_press_reviews',
    'delete_post' => 'delete_press_review')
   ),
   'public' => true,
   'show_ui' => true,
   'publicly_queryable' => true,
   'exclude_from_search' => false,
   'query_var' => true,
   'supports' => array( 'title', 'editor' , 'thumbnail' ),
  )

 );

 add_role('press_dude', 'Press Dude', array(
    'read' => true,
    'edit_press_review' => true,
    'edit_press_reviews' => true,
    'edit_others_press_reviews' => true,
    'publish_press_reviews' => true,
    'read_press_review' => true,
    'read_private_press_reviews' => true,
    'delete_press_review' => true,
        ));
}

On login i get:
