Doctrine2关联属性命令，名称为“几乎相似”的实体

I went through a strange "bug".

I have 2 associations on an entity with "almost the same same" :

/**
 * @ORM\OneToOne(targetEntity="TaxeApprentissage\Entity\Collecteur\Parametres", mappedBy="collecteur")
 */
private $parametres;

/**
 * @ORM\OneToOne(targetEntity="TaxeApprentissage\Entity\Collecteur\ParametresEdition", mappedBy="collecteur")
 */
private $parametresEdition;

When lazy loading happens, I got the exact same object TaxeApprentissage\Entity\Collecteur\ParametresEdition in both properties $parametres and $parametresEdition.

But when I reverse the associations :

/**
 * @ORM\OneToOne(targetEntity="TaxeApprentissage\Entity\Collecteur\ParametresEdition", mappedBy="collecteur")
 */
private $parametresEdition;

/**
 * @ORM\OneToOne(targetEntity="TaxeApprentissage\Entity\Collecteur\Parametres", mappedBy="collecteur")
 */
private $parametres;

Everything is working perfectly. I get the correct object for each association.

Is it caused by the fact that the entities are named almost similar?

It is probably because you made a mistake on the owning side? What do the column definitions on other side (inside Parametres and ParametresEdition) look like? You don't show them in your question.

You probably have twice inversedBy="parametres" or inversedBy="parametresEdition".

@ORM\OneToOne(targetEntity="TaxeApprentissage\Entity\Collecteur\Collecteur", inversedBy="????")

@ORM\OneToOne(targetEntity="TaxeApprentissage\Entity\Collecteur\Collecteur", inversedBy="????")
