Symfony 3.3 как добавить ограничения в collectionType для двух вложенных

У меня есть форма symfony 3.3 с двумя уровнями коллекции типов вложенности. как отследить проверку полей со второго уровня до первого. как отследить валидацию последнего уровня вложенности, то есть поля $ amount в PricingMissionTypeEquipmentType. only @Assert\valid() не работает. Вот мой код

class BillingSetting
{
    /**

     * @ORM\Column(name = "id", type = "integer")

     */
    private $id;

    /**

     * @ORM\JoinColumn(name = "pricing_id", referencedColumnName = "id")

    /**

    /**

    public function __construct()
    {
        $this->pricingMissionTypes = new ArrayCollection();
    }
