I'd like to extend menu controller by adding the function to modify my links:
function myLink() {
   return $this->Link() . "?fv=".$_GET['fv'];
}

I've added it now to: class Page_Controller extends ContentController
the value of $myLink variable shows now on the page but still have empty value
withing menu (take a look below):
<% control Menu(2) %>
$newLink
<% end_control %>

what should I do to get value of $newLink within control Menu(2) ??

thanks in advance
