Jira issue originally created by user nelfo:

Should this:

public function preUpdate(PreUpdateEventArgs $eventArgs)
{
    $entity = $eventArgs->getEntity();
    $em = $eventArgs->getEntityManager();
    $uow = $em->getUnitOfWork();

    if ($entity instanceof User) {
        if ($eventArgs->hasChangedField('finalStatus')) {
            $entity->setFinalStatusDate(new \DateTime('now'));
            $uow->recomputeSingleEntityChangeSet(
                $em->getClassMetadata("MyAdminBundle:User"),
                $entity
            );
        }
        if ($eventArgs->hasChangedField('membershipCode')) {
            $entity->setMembershipCodeDate(new \DateTime('now'));
            $uow->recomputeSingleEntityChangeSet(
                $em->getClassMetadata("MyAdminBundle:User"),
                $entity
            );
        }
    }
}

...result in this?

Catchable Fatal Error: Argument 3 passed to Doctrine\ORM\Event\PreUpdateEventArgs::**construct() must be an array, null given, called in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php on line 995 and defined in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Event/PreUpdateEventArgs.php line 47

I'm just setting a time stamp for two updated values. Dumping the 3rd argument in PreUpdateEventArgs.php on line 47 reveals an array of changes. I'm not sure if this is a bug or if I'm performing this simple operation incorrectly.

Can you write an integration test around it? Looks like the changeset is removed in a particular edge case, but it's hard to figure it out without a test.
