$em->remove($entity) on entity that uses @Id + @ManyToOne generates fatal at UnitOfWork

/****
 * @Entity
 */
class UserData {

    /****
     * @Id
     * @ManyToOne(targetEntity="User")
     */
    protected $user;

    /****
     * @Id
     * @ManyToOne(targetEntity="Article")
     */
    protected $article;

    ......

}

$em->remove($userData);

PHP Catchable fatal error: Object of class User could not be converted to string in /path/to/Doctrine/ORM/UnitOfWork.php on line 2166

Probably because it tries to use UserData primary key properties directly and not detecting that its actually an association.

Line 2166 in version 2.1.2 is a docblock comment.

Can you specifiy this more and potentially add the stacktrace when this warning occurs (xdebug)?
