Symfony using AdvancedUserInterface - symfony

Question

I am trying to implement a login system with Symfony2. I am implementing the AdvancedUserInterface for my User entity, and keep getting the following error when I try to log in. Any help is appreciated.
Error:
$user must be an instanceof UserInterface, an object implementing a __toString method, or a primitive string.
User Entity:
<?php
namespace Flc\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\AdvancedUserInterface;
use Serializable;
/**
* User
*
* #ORM\Table(name="users")
* #ORM\Entity(repositoryClass="Flc\UserBundle\Entity\UserRepository")
*/
class User implements AdvancedUserInterface, Serializable {
/**
* #var integer
*
* #ORM\Column(name="userId", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $userId;
/**
* #var string
*
* #ORM\Column(name="userEmail", type="string", length=50)
*/
private $userEmail;
/**
* #var string
*
* #ORM\Column(name="userName", type="string", length=20)
*/
private $userName;
/**
* #var string
*
* #ORM\Column(name="userPassword", type="string", length=60)
*/
private $userPassword;
/**
* #var string
*
* #ORM\Column(name="userSalt", type="string", length=60, nullable=true)
*/
private $userSalt;
/**

*
* #ORM\Column(name="userFirstName", type="string", length=40)
*/
private $userFirstName;
/**
* #var string
*
* #ORM\Column(name="userLastName", type="string", length=40)
*/
private $userLastName;
/**
* #var string
*
* #ORM\Column(name="userPhone", type="string", length=10)
*/
private $userPhone;
/**
* #var \DateTime
*
* #ORM\Column(name="created", type="datetime")
*/
private $created;
/**
* #var boolean
*
* #ORM\Column(name="isActive", type="boolean")
*/
private $isActive;
/**

*
* #ORM\Column(name="roles", type="json_array", nullable=true)

Answer 1

try adding __toString method on your User entity:
public function __toString() {
return (string) $this->getUsername();
}

Answer 2

In User Repository you need to replace :
public function findOneByUsernameOrEmail($username) {
return $this->createQueryBuilder('u')
->andWhere('u.userName = :username OR u.userEmail = :email')
->setParameter('username', $username)
->setParameter('email', $username)
->getQuery()
->getOneOrNullResult();
}
public function loadUserByUsername($username) {
//$user = $this->findOneByUsernameOrEmail($username);
$user = $this->findOneBy(array("userName"=>$username));
if (!$user) {
throw new UsernameNotFoundException('No user found for ' . $username);
}
return $user;
}
with :
public function loadUserByUsername($username)
{
$q = $this
->createQueryBuilder('u')
->where('u.username = :username OR u.email = :email')
->setParameter('username', $username)
->setParameter('email', $username)
->getQuery();
try {
$user = $q->getSingleResult();
} catch (NoResultException $e) {
throw new UsernameNotFoundException(sprintf('Unable to find an active admin AcmeUserBundle:User object identified by "%s".', $username), 0, $e);
}
return $user;
}
