you're passing whole form view object in url:

$this->redirecttoroute('addaction', array('form' => $form->createview())); 

the second argument redirecttoroute() list of parameters send request.

this makes url long. exceeds web server limit, in turn refuses handle request.

your call should more this:

$this->redirecttoroute('addaction'); 

also, first argument redirecttoroute() method route name, not action method name. replace unless route name "addaction".
