Doctrine2.3 and OneToOne cascade persist doesn't seem to work

Question

I have two entites (User and UserPreferences) that I want to map OneToOne unidirectional.

The code looks something like this:

/**
 * @ORM\\Table(\"us         


        

Answer 1

Bug was with

 * @ORM\Column(name="user_preferences_id", type="integer")

Your code should contain

 * @ORM\JoinColumn(name="user_preferences_id", referencedColumnName="id")

instead of this.

Answer 2

Ok found the solution:

/**
 * User
 *
 * @ORM\Table("users")
 * @ORM\Entity
 */
class User extends UserEntity
{
    ...

    /**
     * @ORM\OneToOne
     * (
     *      targetEntity="UserPreferences",
     *      cascade={"persist", "remove"},
     *      inversedBy="user"
     * )
     */
    protected $userPreferences;
}

/**
 * @ORM\Table("user_preferences")
 * @ORM\Entity
 */
class UserPreferences extends UserPreferencesEntity
{
    /**
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue
     */
    protected $id;

    /**
     * @var int
     *
     * @ORM\OneToOne(targetEntity="User", mappedBy="id", cascade={"persist", "remove"})
     */
    protected $user;

    ...
}

First of all I had to specify mappedBy and inversedBy (which I already tried before but in the wrong direction - mappedBy at the owning side, inversedBy at inversed side). Also I thought that the inversed side did not need to have a separate id and I tried to use the id of the owning side (User#id) as primary key for this one too.
