 Priority:  high          |   Milestone:  3.0  
Component:  Plugins       |     Version:  3.0

 (works in 2.9 not in 3.0)

 Unable to create a 'screen options' tab for plugin admin pages.

 In 2.7, filter ’screen_meta_screen’ was created to give the ability to
 name the $screen variable for plugins.
 (http://core.trac.wordpress.org/changeset/9788)

 In 3.0 the code sequence has changed in wp-admin/includes/template.php,
 for function screen_meta

 new code is :


 if ( is_string($screen) ) $screen = convert_to_screen($screen);


 Result is that with the "is_string" test, for plugins admin pages,
 "convert_to_screen" function is never called  and filter
 ’screen_meta_screen’ is never called ...

 Consequence is : no screen options tab and corresponding div’s for plugin
 admin pages.
