I am using an eventSubscriber to dynamically load a field (Patient) in a form, of which in its preSubmit function I need to obtain in addition to the id the patient's ID. The id can be obtained directly, but the ID I need to bring the entity, and I do not know how I can do it from here.

My event in question is the following:

class AddHistoriaClinicaFieldSubscriber implements EventSubscriberInterface
{
    private $propertyPathToHistoriaClinica;
    public function __construct($propertyPathToHistoriaClinica)
    {
        $this->propertyPathToHistoriaClinica = $propertyPathToHistoriaClinica;
    }
    public static function getSubscribedEvents()
    {
        return array(
            FormEvents::POST_SET_DATA => 'preSetData',
            FormEvents::PRE_SUBMIT    => 'preSubmit'
        );
    }
    private function addHistoriaClinicaForm($form, $paciente_id)
    {
        $formOptions = array(
            'class'         => 'BiobancoBundle:HistoriaClinica',
            'empty_value'   => '-- SELECCIONAR HISTORIA CLINICA --',
            'label'         => 'Historia Clínica',
            'attr'          => array(
                'class' => 'historia_clinica_selector',
            ),
            'query_builder' => function (EntityRepository $repository) use ($paciente_id) {
                $qb = $repository->createQueryBuilder('h')
                    ->innerJoin('h.paciente', 'p')
                    ->where('p.id = :p')
                    ->setParameter('p', $paciente_id)
                ;
                return $qb;
            },
        );
        $form->add($this->propertyPathToHistoriaClinica, 'entity', $formOptions);
    }
    public function preSetData(FormEvent $event)
    {
        $data = $event->getData();
        $form = $event->getForm();
        if (null === $data) {
            return;
        }
        $accessor    = PropertyAccess::createPropertyAccessor();
        $h        = $accessor->getValue($data, $this->propertyPathToHistoriaClinica);
        $paciente_id = ($h) ? $h->getPaciente()->getNumeroIdentificacion() : null;
        $this->addHistoriaClinicaForm($form, $paciente_id);
    }
    public function preSubmit(FormEvent $event)
    {
        $data = $event->getData();
        $form = $event->getForm();
        $paciente_id = array_key_exists('paciente', $data) ? $data['paciente'] : null;
        //AQUÍ ES DONDE NECESITO OBTENER EL DNI, PARA PASARLO AL FORMULARIO
        //dump($data);die();
        $this->addHistoriaClinicaForm($form, $paciente_id);
    }
}

EDIT 1 OF preSubmit:

use Doctrine\ORM\Event\LifecycleEventArgs;

...

public function preSubmit(FormEvent $event, LifecycleEventArgs $args)
    {
        $data = $event->getData();
        $form = $event->getForm();
        $paciente_id = array_key_exists('paciente', $data) ? $data['paciente'] : null;
        dump($args->getEntityManager()->getRepository("BiobancoBundle:Paciente")->find($paciente_id));die();
        $this->addHistoriaClinicaForm($form, $paciente_id);
    }

The error, jumps in the line of the declaration of the function, when injecting LifecycleEventArgs

In the official symfony documentation you will find this to call the entity from eventSubscriber

public function getSubscribedEvents()
{
    return array(
        'postPersist',
        'postUpdate',
    );
}

public function postUpdate(LifecycleEventArgs $args)
{
    $this->index($args);
}

public function postPersist(LifecycleEventArgs $args)
{
    $this->index($args);
}

public function index(LifecycleEventArgs $args)
{
    $entity = $args->getEntity();

    // perhaps you only want to act on some "Product" entity
    if ($entity instanceof Product) {
        $entityManager = $args->getEntityManager();
        // ... do something with the Product
    }
}

Simply calling the entity you could invoke it and then changing the parameters indicated by the documentation should work

I have found more explicit documentation, maybe adding all the methods stop jumping the error
