Symfony 2：服务依赖性失败

Question

Since yesterday, I can't understand why i have this error on my Symfony website. I have a service which depends on others. When i try to use and inject the Symfony doctrine entity manager i have errors. I can't find a way to do it :(

My config :

mycompany_jobs_bundle.processor.crm.product_matrix:
    class: %mycompany_jobs_bundle.processor.crm.product_matrix.class%
    parent: pim_base_connector.processor.product_to_flat_array
    arguments:
      - '@pim_catalog.repository.attribute'
      - '@pim_catalog.localization.factory.date'
      - '@doctrine.orm.default_entity_manager'

(I also tried 'doctrine.orm.entity_manager' instead of '@doctrine.orm.default_entity_manager' -> same results)

Then, in my service :

• I add a "use Doctrine\ORM\EntityManager;" with the other "use" lines.
• And this is my constructor :

... but i have this error :

Catchable Fatal Error: Argument 8 passed to Mycompany\Bundle\JobsBundle\Processor\Mycompany\ProductWordMatrixProcessor::__construct() must implement interface Pim\Component\Catalog\Repository\AttributeRepositoryInterface, instance of Doctrine\ORM\EntityManager given

Wherever i move my line "EntityManager $em" i have error with arguments position. What's wrong ? I can't understand ..

Thanks for your help

Edit : below the yml config of the parent service, pim_base_connector.processor.product_to_flat_array :

pim_base_connector.processor.product_to_flat_array:
   class: %pim_base_connector.processor.product_to_flat_array.class%
   arguments:
       - '@pim_serializer'
       - '@pim_catalog.manager.channel'
       - '@pim_catalog.builder.product'
       - ['pim_catalog_file', 'pim_catalog_image']
       - %pim_catalog.localization.decimal_separators%
       - %pim_catalog.localization.date_formats%
       - '@akeneo_storage_utils.doctrine.object_detacher'

Answer 1

Try to move the EntityManaer as the last parameter of your constructor arguments like this:

public function __construct()
{
   //.. others
   AttributeRepositoryInterface $attributeRepository,
   EntityManager $em
}

You need to maintain the order of your dependencies declared inside the configuration
