symfony : can't we have a hidden entity field?

Question

I am rendering a form with an entity field in symfony.

It works well when i choose a regular entity field.

$builder
    ->add(\'parent\',\'entity\

A quick solution whitout creating new transformer and type classes. When you want to prepopulate an related entity from the db.

// Hidden selected single group
$builder->add('idGroup', 'entity', array(
    'label' => false,
    'class' => 'MyVendorCoreBundle:Group',
    'query_builder' => function (EntityRepository $er) {
        $qb = $er->createQueryBuilder('c');
        return $qb->where($qb->expr()->eq('c.groupid', $this->groupId()));
    },
    'attr' => array(
        'class' => 'hidden'
    )
));

This results a single hidden selection like:

    MyGroup

But yes, i agree that with a little more effort by using a DataTransformer you can achieve something like:
