How to access Sonata admin pool in form type

Question

Use case

I' m trying to reuse sonata_type_model_list in the front admin of my website by defining this in my buildForm method of my Entity FormType :

[...]
->add('position', 'sonata_type_model_list', array(
      'model_manager' => $categoryManager,
))
[...]

However I can't use

$categoryAdmin = $this
    ->getConfigurationPool()
    ->getAdminByClass("\\Application\\Sonata\\ClassificationBundle\\Entity\\Category");

As I need to be in an AdminClass to use getConfigurationPool().

If anyone knows how to use getConfigurationPool() outside of an AdminClass or do you know how to declare sonata_type_model_list in order to use it outside of an admin class ?

Thanks to @pbenard & @Mawcel for their answers, I combined them to achieve my goal as follow:

In my controller I create my form and inject $this->container->get('sonata.admin.pool') to it like so :

$form = $this->createForm(
    new FormType($this->container->get('sonata.admin.pool')), 
    $entity, 
    $options
);

In my formType, I added the property $adminPool && the __construct method:

private $adminPool;

public function __construct(Pool $adminPool) {
    $this->adminPool = $adminPool;
}

So I can now access the adminPool from the buildForm method:

public function buildForm(FormBuilderInterface $builder, array $options)
{
    [...]
    $categoryAdmin = $this
        ->getConfigurationPool()
        ->getAdminByClass("\\Application\\Sonata\\ClassificationBundle\\Entity\\Category"        );
    [...]
}
