HI, it seems the :overwrite_params option has disappeared from the url_builder. Is there a reason or is it just a side effect of the new routes? Any chances to see it coming back? If that matters, I use it a lot :-) Raph PS: For those who don''t know it, it lets you use the current @params as parameters for eg link_to, just overwriting the values you want. For example, when displaying a long list on different pages, the only parameter changing in the url is the page number and you can just do: link_to ( :overwrite_params => {"page_number" => @next_page_number}) working like link_to (:params => @params.update {"page_number" => @next_page_number} ) is not practical as you have to deal with the id, action and controller (which are in @params too)
