CPagination, additional query params

I need to add to pages refs additional query params, and I have tried

$pages->route = 'contr/act&param=' . $value;

But this isn’t consistent with flatten url style (‘path’ format). Ok, you can say, I can check the format, and I can :) But, probably more direct way to add additional params to query string (or path) exists. Is there such one?

Change $_GET.

Aha, catched up, thanks! OTOH, CHtml::form() uses request url rather $_GET for default action. What are reasons of different approaches?

form() doesn't need to change the URL, while CPagination needs to insert page parameter.

My form does  :) - I have met a case when I want to remove one request parameter form an action.
