Wordpress custom post type capabilities, admin can't edit post type -

i'm having wired problem wordpress. below code events post type, works without capabilities when capabilities added default roles (admin, editor, etc...) cant use post type. admin role able see custom taxonomies.

i have custom user role "edit_events => true" user role able submit events review. want, built in roles can't see post type!

i've tried every capabilities tutorial find, seem pretty same , can't how of them differ code.

function register_custom_event_type() { $labels = array(     'name' => _x('events', 'event'),     'singular_name' => _x('event', 'event'),     'add_new' => _x('add new', 'event'),     'add_new_item' => _x('add new event', 'event'),     'edit_item' => _x('edit event', 'event'),     'new_item' => _x('new event', 'event'),     'view_item' => _x('view event', 'event'),     'search_items' => _x('search events', 'event'),     'not_found' => _x('no events found', 'event'),     'not_found_in_trash' => _x('no events found in trash', 'event'),     'parent_item_colon' => _x('parent event:', 'event'),     'menu_name' => _x('events', 'event'), );  $args = array(     'labels' => $labels,     'hierarchical' => false,     'supports' => array('title', 'editor', 'thumbnail', 'author'),     'public' => true,     'show_ui' => true,     'show_in_menu' => true,     'show_in_nav_menus' => true,     'publicly_queryable' => true,     'exclude_from_search' => false,     'has_archive' => true,     'query_var' => true,     'can_export' => true,     'rewrite' => true,     'capability_type' => 'event',     'capabilities' => array(             'read_post' => 'read_event',             'publish_posts' => 'publish_events',             'edit_posts' => 'edit_events',             'edit_others_posts' => 'edit_others_events',             'delete_posts' => 'delete_events',             'delete_others_posts' => 'delete_others_events',             'read_private_posts' => 'read_private_events',             'edit_post' => 'edit_event',             'delete_post' => 'delete_event',          ),     'map_meta_cap' => true ); register_post_type('event', $args); } add_action('init', 'register_custom_event_type'); 

i found work around in end.

i thought default wordpress roles have same capabilities post type normal post, reason don't.

adding capabilities manually seems work.

function add_event_caps() { $role = get_role( 'administrator' );  $role->add_cap( 'edit_event' );  $role->add_cap( 'edit_events' );  $role->add_cap( 'edit_others_events' );  $role->add_cap( 'publish_events' );  $role->add_cap( 'read_event' );  $role->add_cap( 'read_private_events' );  $role->add_cap( 'delete_event' );  } add_action( 'admin_init', 'add_event_caps');
