Symfony FromEvents 1 argument must be an instance of

The error here is not explicit, from what I think it is related just to a Type difference between parameters but i have not found the way to resolve this... The EventListener is receiving 2 parameters but it doesn't provide the information of which of them is the "1" argument with the issue but I think it is the 2nd due to the error says an instance of UserBundle\Form\FormEvent on singular and the first argument is a generic event from the FormEvents class which is on plural.

Error Shown:

Type error: Argument 1 passed to UserBundle\Form\UserType::UserBundle\Form{closure}() must be an instance of UserBundle\Form\FormEvent, instance of Symfony\Component\Form\FormEvent given

<?php

You're missing the FormEvent class import.

use Symfony\Component\Form\FormEvent;

Since you did not import it, it used the current namespace for the class (UserBundle\Form\FormEvent). But this class doesn't exist.
