How to use ValueResolver in another ValueResolver or chain ValueResolver with Symfony

Question

I'm using Symfony 6.2 with php 8.1.

Since the update of SF 6.2 i had to remove SensioFrameworkExtraBundle and migrate my code from ParamConverter to new custom ValueResolver.

However, i'm facing a lack a feature from this migration or i miss something :(

With a custom ParamConverter, i could resolve a parameter and rewrite the new content in the Request. This allow me to chain any ParamConverter. The new way with custom ValueResolver does not rewrite the content in the Request. Of course i can force to rewrite the content or create a new attribute in the Request but i feel it's wrong or not proper way.

My use case :

The resolver for TranslationKey need the resolver result of TranslationDomain and TranslationLanguage. basically i would like to chain these resolver or group them like we can do in form Constraint.

services.yaml

App\Service\\ranslation\Request\ValueResolver\TranslationLanguageValueResolver:  
  tags:  
    - { name: controller.argument_value_resolver, priority: 103 }  
  
App\Service\Translation\Request\ValueResolver\\TranslationDomainValueResolver:  
  tags:  
    - { name: controller.argument_value_resolver, priority: 102 }  
  
App\Service\Translation\Request\ValueResolver\TranslationKeyValueResolver:  
  tags:  
    - { name: controller.argument_value_resolver, priority: 101 }

My controller :

public function edit (Request             $request,  
   TranslationLanguage $translationLanguage,  
   TranslationDomain   $translationDomain,  
   TranslationKey      $translationKey,  
   TranslationHelper   $translationHelper,  
   Translation         $translation): Response
{
    [some code]
}

TranslationKeyValueResolver :

public function resolve (Request $request, ArgumentMetadata $argument): iterable  
{  
    $argumentType = $argument->getType();  
 if (!$argumentType || !($argumentType === TranslationKey::class)) {  
        return [];  
   }  
  
   $translationLanguage = $request->get('translationLanguage'); //=> does not return the object since it's not chained
    [some code]
    
    return [new TranslationKey($translationKey)];
}

Before :

    public function apply(Request $request, ParamConverter $configuration)
    {
        [some code]

        $request->attributes->set($configuration->getName(), new TranslationLanguage($languages));

        return true;
    }

After :

public function resolve (Request $request, ArgumentMetadata $argument): iterable  
{  
    $argumentType = $argument->getType();  
 if (!$argumentType || !($argumentType === TranslationLanguage::class)) {  
        return [];  
   }  
  
    [some code]
  
 return [new TranslationLanguage($languages)];
}

So, i tried to create a new attribute in Request with the new value, but it feel terribly wrong since it suppose all resolver has been executed before and in order. But it's working.

I though to revolve again TranslationLangage and TranslationDomain in TranslationKeyValueResolver but i don't know how, neither what tag i should set in that case ? Custom tag ?

App\Service\Translation\Request\ValueResolver\TranslationKeyValueResolver:  
  tags:  
    - { name: controller.argument_value_resolver, priority: 101 }
    - { name: another_tag_to_resolve_argument_from_resolver, priority: 101 } ??

Any idea please ?

Radyium Thanks
