Custom post_type with custom capabilities

[luisarn]

Hi! I found an issue on my custom post type with custom capabilities such as:

` 'capability_type' => 'events',
'capabilities' => array(
// Meta capabilities
'edit_post' => 'event_edit',
'read_post' => 'event_read',
'delete_post' => 'event_delete',

    // Primitive capabilities used outside of map_meta_cap():

    'edit_posts' => 'events_edit',
    'edit_others_posts' => 'events_edit_others',
    'publish_posts' => 'events_publish',
    'read_private_posts' => 'events_read_private',

    // Primitive capabilities used within map_meta_cap():

    'read' => 'read',
    'delete_posts' => 'events_delete',
    'delete_private_posts' => 'events_delete_private',
    'delete_published_posts' => 'events_delete_published',
    'delete_others_posts' => 'events_delete_others',
    'edit_private_posts' => 'events_edit_private',
    'edit_published_posts' => 'events_edit_published',
    'create' => 'events_edit',
),`

Those custom capabilities are not being copied to the alternate post and if an user without the default edit_post cap won't be able to view or edit the alternate version.

I managed to fix the issue by adding the following line on the line 414 of bu-versions.php:

$args['cap'] = $type->cap;

I don't know if it will have any impact in your design but if not maybe you could include this update in your next version?

Best regards,
