Symfony2: Query the database with Doctrine - symfony

Question

I have a small database connected with my Symfony2 project. I have my controller, the entity etc.
When I try to use the method find(), I am allways obtaining a null.
Here is how the find method is called:
public function loginsuccessAction()
{
$em = $this->getDoctrine()->getEntityManager();
$user = $em->getRepository('MDPILoginBundle:Users')->find(1);
var_dump($user);
}
My Users entity class has the needed getters and setters. My table Users is well populated.
What am I missing ? New with symfony, I am trying to do it for the first time, reading some tutorials.
Thank you very much.
PS: If you need more details, please feel free to ask me.
EDIT: Entity Users.php added
Here is the Users.php entity

Answer 1

Make sure the value you are using in the find method is the same as the defined primary key ( #ID ) in your entity.
