ParamConverter | ParamConverter from SensioFrameworkExtraBundle | Web Framework library

I use Symfony 5 and have a trouble with the ParamConverter bundle when I try to map request to my DTO class. In my controller I use create method:

I have a form for add users on my event, but when I add the user I try to add a role on this event, but I get this fail when the second function is executed

App\Entity\Evento object not found by the @ParamConverter annotation.

I don't see the problem, thanks

I'm trying to write a controller that doesn't extend Symfony's "classic" AbstractController and I'd like to use the ParamConverter inside as an annotation. The controller code is as follows:

I want to display in Twig a string list of "strenghts" for a "strategy" that I get in the controller with ParamConverter (there is a one to many relation, and "strenghts" is an attribute in strategy as an array collection).

I could make it work in the controller to get the right data in my twig file (verified with a dump), but nothing is displayed in Twig (and yes data is written in database, and I checked it's not a front problem).

So I have read many topics about the same problem, and a lot of them say that I have to loop on the array collection to be able to display it in strings, which I tried but couldn't make it work.

Controller file :

I was trying to create a Payload where one of the fields is Collection of another objects. So I created something like this.

I would like to merge two routes with ParamConverters on Symfony 5. On the root route I want to get all the records from the Entity table. On the id route I want to get only that particular Id. But as I access the root route i get this Exception: "Unable to guess how to get a Doctrine instance from the request information for parameter "cronjob". "

I try to be redirected after modifying the comment but I have the error App \ Entity \ Article object not found by the @paramconverter annotation do you have any idea of ​​the problem?

I wanted to put in my controller a second delete button to delete comments but I got lots of error messages like the one from ParamConverter because it did not recognize the class.

So in my controller I have a ParamConverter like this:

The last composer update completely broken my project based on Symfony5:

php.CRITICAL: Uncaught Error: Argument 1 passed to Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter\DoctrineParamConverter::__construct() must be an instance of Doctrine\Common\Persistence\ManagerRegistry or null, instance of Doctrine\Bundle\DoctrineBundle\Registry given

I've already updated all the references of Doctrine\Bundle\DoctrineBundle\Registry to Doctrine\Common\Persistence\ManagerRegistry a long time ago, according to the Symfony documentation

Any help would be appreciated
