Doctrine Blameable：on =“change”在on =“create”和“update”时不起作用

Question

我正在尝试将Doctrine的Extensions Blameable和Softdeleteable结合起来：当我执行$em->remove($myEntity);时，我希望相应地更新字段deleted和deletedBy。

use Gedmo\Mapping\Annotation as Gedmo;

/**
 * @Gedmo\SoftDeleteable(fieldName="deleted", timeAware=false)
 */

[...]

/**
 * DateTime of softdeletion
 * @var \DateTime
 * 
 * @ORM\Column(name="deleted", type="datetime", nullable=true)
 * @Assert\DateTime()
 */
private $deleted;

/**
 * Softdeleted by
 * @var MyProject\UserBundle\Entity\User $deletedBy
 *
 * @Gedmo\Blameable(on="change", field="deleted")
 * @ORM\ManyToOne(targetEntity="MyProject\UserBundle\Entity\User")
 * @ORM\JoinColumn()
 */
private $deletedBy;

我对created / createdBy（使用Blameable(on="create")）和updated / updatedBy（使用Blameable(on="update")）进行了类似的配置。

即使更奇怪，如果我用上面的代码替换上面的代码，字段deletedBy也会正确更新：

/**
 * Softdeleted by
 * @var MyProject\UserBundle\Entity\User $deletedBy
 *
 * @Gedmo\Blameable(on="update")
 * @ORM\ManyToOne(targetEntity="MyProject\UserBundle\Entity\User")
 * @ORM\JoinColumn()
 */
private $deletedBy;

所以似乎只有Blameable(on="change", field="deleted")部分不起作用，我不知道为什么......
