Symfony Dynamic class names are not allowed in compile-time

I am trying to initialize dynamically a form. The form name is stored in $obj->getFormTypeName().

$formName = 'Acme\testBundle\Form\CustomType\\'.ucfirst($obj->getFormTypeName()).'Type';
$contactForms[$obj->getId()] = $this->createForm($formName::class);

But I get the error : Compile Error: Dynamic class names are not allowed in compile-time ::class fetch

Is there a way to initialize dynamically a form with the Scope Resolution Operator in Symfony ?

Thanks for reading.

One should not want to call a ::class on a variable, string name of the class eg. Acme\testBundle\Form\CustomType\FormType like this

'Acme\testBundle\Form\CustomType\'::class, as in the end the string var of the class, it's the classname itself.

Something similar is possible only in Javascript to my knowledge 'stringContents'.val()

To get around this issue, I'd do something like:

$contactForms[$obj->getId()] = $this->createForm(
    'Acme\\testBundle\\Form\\CustomType\\' . ucfirst($obj->getFormTypeName()) . 'Type'
);

After all, ::class only returns the fully qualified name of the class.
