}
its working fine but i keep getting those errors and have no clue in how to get rid of them.

Answer 1

This is a very common question for people who are new to dependency injection containers. You defined your service but then used new RegistroType() to create the instance. The thinking is that php will somehow realize that you want a service and use the container. Nope. The 'new' operator knows nothing about the service container and simply tries to create a new instance without any parameters. Hence the error message.
You obviously read the "defining form type as a service" section (http://symfony.com/doc/current/book/forms.html#defining-your-forms-as-services) and I can see where your confusion comes from. The manual could be a bit clearer perhaps.
Bottom line is that you need to use the form type's alias instead of the new operator:
// Replace
$formulario = $this->createForm(\sava\UserBundle\Form\RegistroType(),$User);
// With
$formulario = $this->createForm('sava_user_registration',$User);
You will get a different error the first time you try this. You have a typo in your service definition but I'll leave that for you to debug.
