but an exception keep appearing:
Catchable Fatal Error: Argument 1 passed to Sylius\Bundle\ResourceBundle\Controller\ResourceController::__construct() must implement interface Sylius\Component\Resource\Metadata\MetadataInterface, none given, called in C:\wamp3\www\sidratsoft_website\app\cache\dev\appDevDebugProjectContainer.php on line 1382 and defined

Answer 1

I suppose you don't have to register controller as service in AppBundle/Resoures/config/services.yml. As you extend ResourceController (which is totally correct) it has to have many dependency injected - fortunately , you don't have to inject them yourself, as Sylius will do the job and automatically register controller with dependencies injected.

i thiink i fixed it, the problem was in the _controller attribute in the routing :
from this :
app_bundle_product:
path: /products/cat/{taxon}
defaults:
_controller: AppBundle:Product:allProdSpecificTaxonAction
to:
app_bundle_product:
path: /products/cat/{taxon}
defaults:
_controller: sylius.controller.product:allProdSpecificTaxonAction
