How to add context help to custom admin plugin page? Some time ago I had to put help content to custom admin plugin page for my project.

There are pretty good examples at wordpress.org . Here is one of those examples :

<?php 
add_action('admin_menu', 'my_admin_add_page');

function my_admin_add_page() {
    $my_admin_page = add_options_page(__('My Admin Page', 'map'), __('My Admin Page', 'map'), 'manage_options', 'map', 'my_admin_page');

    // Adds my_help_tab when my_admin_page loads
    add_action('load-'.$my_admin_page, 'my_admin_add_help_tab');
}

function my_admin_add_help_tab () {
    $screen = get_current_screen();

    // Add my_help_tab if current screen is My Admin Page
    $screen->add_help_tab( array(
        'id'	=> 'my_help_tab',
        'title'	=> __('My Help Tab'),
        'content'	=> '<p>' . __( 'Descriptive content that will show in My Help Tab-body goes here.' ) . '</p>',
    ) );
}
?>

This is working fine if you want to add context help to your custom option page within settings menu or to your custom post type. But if you have empty admin page then probably will nothing happened like in my case. Why is that?
