Plugin Dvpt (submenu issue)

Hi !

I have developped a plugin in order to capture events
from anybody like comments.

The admin part of the “event” plugin is very similar to the
comments management (list of event, moderate event, modify event etc …).

Before WP 2.2 i could handle the display of different panels using url like these :
/wp/wp-admin/edit-comments.php?page=wp-content/plugins/MyAgenda/php/event.php&action=editevent&event=6&call1st=edit-events.php&mode=view

This kind of url doesn’t work anymore for WP versions > 2.2

Does anybody have an idea how to implement a ‘comment management like’ items under the Comment menu ?

Help appreciated.

Thanks
