[Flow] Setting cookie inside a widget controller action?

[Christian Loock]

Hi,

is there a way to set a cookie inside a Widget Controller? I tried 
something like this, which does not seem to work:

         $httpRequest = $this->request->getHttpRequest();
         if ($httpRequest->hasCookie('systemLanguage')) {
             $cookie = $httpRequest->getCookie('systemLanguage');
         } else {
             $cookie = new \TYPO3\Flow\Http\Cookie('systemLanguage');
         }
         $cookie->setValue($locale);
         $this->response->setCookie($cookie);


Is there something special about widget controllers that this does not 
work? When I do the same in a normal controller, it works just like you 
would expect it to.

Cheers,

Christian
