Issue in uploading the Picture

Hi,
When i try to upload a picture i get an error 

"Started POST "/attachments/create.js?media=print" for 127.0.0.1 at Thu Feb 10 18:51:54 +0530 2011

ActionController::RoutingError (No route matches "/attachments/create.js"):"

The "/attachments/manage" works fine but it seems there is some problem with create

I have already used it on rails 2 but is there any problem with rails 3 ?
