getUser() returns null, session is not started in my symfony controller

Question

On the latest Symfony 2 version (using FOSUserBundle and SonataUserBundle), I am trying to get the current user in order to pre-fill a form in my new Entity controller.

On mycontroller.yml :

my_controller_new:
    pattern:  /new
    defaults: { _controller: "MySiteBundle:MyController:new" }

On MyController.php :

public function newAction()
{
  $user = $this->getUser();
  // ...
}

But when I call $this->getUser() , the method returns null . Even though I am logged in (I can access /profile and update my user info without any problem)

I then tried to check is the session was started:

public function newAction()
{
  var_dump($this->get('session')->isStarted());
  // ...
}

It returns false. What is wrong here?

Answer 1

public function newAction() { 

        $session = $this->getRequest()->getSession(); // Get started session
        if(!$session instanceof Session)
            $session = new Session(); // if there is no session, start it

        $value = $session->getId(); // get session id
    }
