Well there is some more info, it seems to me that WP_List_Table just returns empty values. The following is the content of $wp_list_table, any ideas?:

object(WP_Posts_List_Table)#8848 (10) { 
    ["hierarchical_display"]=> NULL 
    ["comment_pending_count"]=> NULL 
    ["user_posts_count"]=> NULL 
    ["sticky_posts_count"]=> int(0) 
    ["items"]=> NULL 
    ["_args"]=> array(4) {

    } 
    ["_actions"]=> NULL ["_pagination"]=> NULL 
}

When I use a prompt to show the $action value it is always empty, which means the rest of the script does not fire. Any idea here?

So I am trying to get a custom bulk action to work in Wordpress 3.7.1 and so far no luck. The basis I am using is http://www.skyverge.com/blog/add-custom-bulk-action, and it goes wrong here:

$wp_list_table = _get_list_table('WP_Posts_List_Table'); $action = $wp_list_table->current_action();

THe action itself is added with jQuery and does show. When I use a prompt to show the $action value it is always empty, which means the rest of the script does not fire. Any idea here?
