If you are doing a link with a url, there not much what can be done, you would need to parse the named params array and attach to the link, but, if you are using the helper with an array specifying controller / action, the solution is simple:
$this->Html->link(‘My Link’, array_merge($this->params[‘named’], array(‘controller’ => ‘controller’, ‘action’ => ‘index’)));
This is very useful if you are passing named params between pages or if you want to keep some search criteria among pages (ex. when you have a pagination and a view and edit page, to return to the last landed page of the pagination).
Have fun (and maybe some cake :P)
