Question

I need to modify some fields in my form (label and class), based on whether the entity is the latest published version or not. So I need to be able to inject the entity mana

Answer 1

declare your form type as service:

...
Gutensite\CmsBundle\Form\Type\ViewVersionType
  
  

...

in your form type:

...
private $em;

public function __construct(EntityManagerInterface $entityManager) {
    $this->em = $entityManager;
}

or ou can inject whole container and use it like this:

$this->container->get('doctrine')->getManager('cms'); // or billing
