update schema: doesn't work on a child entity - symfony

Question

This is an entity that inherits a BaseUser:
namespace Dolphine\UserBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="fos_user")
*/
class User extends BaseUser
{
/**
* #var string
*
* #ORM\Column(name="firstname", type="string", length=255)
*/
protected $firstname;
/**
* #var string
*
* #ORM\Column(name="lastname", type="string", length=255)
*/
protected $lastname;
/**
* #var string
*
* #ORM\Column(name="facebookId", type="string", length=255)
*/
protected $facebookId;
public function serialize()
{
return serialize(array($this->facebookId, parent::serialize()));
}
public function unserialize($data)
{
list($this->facebookId, $parentData) = unserialize($data);
parent::unserialize($parentData);
}
/**
* #return string
*/
public function getFirstname()
{
return $this->firstname;
}
/**
* #param string $firstname
*/
public function setFirstname($firstname)
{
$this->firstname = $firstname;
}
/**
* #return string
*/
public function getLastname()
{
return $this->lastname;
}
/**
* #param string $lastname
*/
public function setLastname($lastname)
{
$this->lastname = $lastname;
}
/**
* Get the full name of the user (first + last name)
* #return string
*/
public function getFullName()
{
return $this->getFirstname() . ' ' . $this->getLastname();
}
/**
* #param string $facebookId
* #return void
*/
public function setFacebookId($facebookId)
{
$this->facebookId = $facebookId;
$this->setUsername($facebookId);
}
/**
* #return string
*/
public function getFacebookId()
{
return $this->facebookId;
}
/**
* #param Array
*/
public function setFBData($fbdata)
{
if (isset($fbdata['id'])) {
$this->setFacebookId($fbdata['id']);
$this->addRole('ROLE_FACEBOOK');
}
if (isset($fbdata['first_name'])) {
$this->setFirstname($fbdata['first_name']);
}
if (isset($fbdata['last_name'])) {
$this->setLastname($fbdata['last_name']);
}
if (isset($fbdata['email'])) {
$this->setEmail($fbdata['email']);
}
}
}
After running schema:update --force I get "no changes available for entities", yet my DB table "fos_user" doesn't contain the given fields above.

Answer 1

It appears I had configuration of the bundle set to yml instead of annotations.
