Optimistic locking fails because Doctrine cannot d

Question

I use Doctrine 2 and want to use optimistic locking. It fails with an OptimisticLockException and the error message is The optimistic lock failed, version 1 was expected, but is actually. Please not, that the error message stops after the "actually". It seems Doctrine is not able to determine the version of the entity.

My simplified entity code is:

<?php
declare(encoding='UTF-8');

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table( name = "person" )
 */
class Person extends Entity  {

  /**
   * @param \string $firstName
   */
  public function __constructor( $firstName ) {
    parent::__constructor();
    $this->id = null;
    $this->revision = 0;
    $this->setFirstName( $firstName );
  }

  /**
   * @return int|null The id of the entity
   */
  public function getId() {
    return $this->id;
  }

  /**
   * @return int The revision of the entity
   */
  public function getRevision() {
    return $this->revision;
  }

  /**
   * @return \string The first name
   */
  public function getFirstName() {
    return $this->firstName;
  }

  /**
   * @param \string $newFirstName The new first name
   * @return Person The object itsself for function chaining
   */
  public function setFirstName( $newFirstName ) {
    $this->firstName = $newFirstName;
    return $this;
  }

  /**
   * @ORM\Id
   * @ORM\Column( name = "id", type = "integer" )
   * @ORM\GeneratedValue( strategy = "SEQUENCE" )
   * @var int
   */
  protected $id = null;

  /**
   * @ORM\Version
   * @ORM\Column( name = "rev", type = "integer" )
   * @var integer
   */
  protected $revision = null;

    /**
   * @ORM\Column( name = "firstname", type = "string", nullable = false )
   * @var \string
   */
  protected $firstName = null;
}

?>

Further note, that the correct revision (or version) is loaded into the entity. It equals 1 and can be obtained by getRevision(). Hence, it is not a database error.

The code that triggers the exception is:

$em = $this->getDoctrine()->getManager();
$rep = $this->getDoctrine()->getRepository('HEKdbBundle:Person');
$person = $rep->find( $id );
$rev = $person->getRevision();
$em->lock( $person, LockMode::OPTIMISTIC, $rev );

The (shortened) backtrace is:

1. at OptimisticLockException ::lockFailedVersionMismatch (object(Person), '1', null)

   in /srv/www/matthiasn/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php at line 2320

2. at UnitOfWork ->lock (object(Person), '1', '1')

   in /srv/www/matthiasn/vendor/doctrine/orm/lib/Doctrine/ORM/EntityManager.php at line 747

3. at EntityManager ->lock (object(Person), '1', '1')

   in /srv/www/matthiasn/src/HEK/HEKdbBundle/Controller/PersonController.php at line 173

As one can see, it is not a problem of the $rev variable. It perfectly equals 1. Actually line 2317 of UnitOfWork.php

$entityVersion = $class->reflFields[$class->versionField]->getValue($entity);

fails. $entityVersion equals null. But I do not know why, because the partial expression $class->versionField is "revsion". So it is not a problem of the annotation of my entity.

In case anybody can make some sense out of it, here is the var_dump output of $class$:

Answer 1

The solution was trivial. Lazy loading tricked me. It seems that ->find does not really load the entity from database, but that this is postponed until one access the first attribute of the entity. If I insert a $person->getFoo(), whereby "Foo" denotes any arbitrary, valid property, after the ->find and before the ->lock it works as expected.
