You're passing a form object to createForm. You must pass the name of the class, not the object itself. E.g.: RegistrationUserOneFormType::class

[saddem0]

in services.yml or config.yml? because that's the only place where "AppBundle\Form\Type\RegistrationUserOneFormType" is mentioned.

[garak]

Looks like you're using Symfony 3. I'm afraid that that is not supported, for now.

[saddem0]

Yes i use symfony 3, thanks anyway.

If you want to fix this just go to this file: https://github.com/PUGX/PUGXMultiUserBundle/blob/master/Model/UserDiscriminator.php#L146

and for method getFormType($name) just return the $className var.
