FormView in Twig lose submitted data when render the form - symfony

Question

I use the symfony 2.7.6 full stack framework.
When i submit a form, in the controller i get all submitted data, but in the view there is nothing, an empty form is rendered,something is wrong, i should display the submitted form with errors. but no data and no errors are shown in the twig form...
After hours of debuging of symfony, i can not resolve the problem.
Here is the form Type which is decalred as service:
<?php
namespace Skonsoft\ModelBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormEvents;
use Doctrine\Common\Persistence\ObjectManager;
use Skonsoft\UserBundle\Entity\User;
class ConversationType extends AbstractType
{
/**
* #var \Doctrine\Common\Persistence\ObjectManager
*/
private $om;
/**
* #var TokenStorageInterface
*/
protected $tokenStorage;
/**
* Constructor
*
* #param ObjectManager $om
* #param TokenStorageInterface $tokenStorage
*/
public function __construct(ObjectManager $om,
TokenStorageInterface $tokenStorage)
{
$this->om = $om;
$this->tokenStorage = $tokenStorage;
}
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('message')
->add('advert', 'entity_hidden',
array(
'class' => 'SkonsoftModelBundle:Advert',
'data_class' => null,
'data' => $options['data']->getAdvert()
))
;
$addUser = function(FormBuilderInterface $builder, User $user, $call) {
$builder->addEventListener(FormEvents::PRE_SET_DATA,
function(FormEvent $event) use ($user, $call) {
$entity = $event->getData();
$entity->$call($user);
});
};
$from = $options['data']->getFrom();
if (!$from) {
$from = $this->om->getRepository('SkonsoftUserBundle:User')->find($this->tokenStorage->getToken()->getUser()->getId());
}
$to = $options['data']->getTo();
if (!$to) {
$advert = $this->om->getRepository('SkonsoftModelBundle:Advert')->find($options['data']->getAdvert());
$to = $advert->getUser();
}
$addUser($builder, $from, 'setFrom');
$addUser($builder, $to, 'setTo');
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Skonsoft\ModelBundle\Entity\Conversation'
));
}
/**
* #return string
*/
public function getName()
{
return 'ss_conversation';
}
}
An this is the controller action:
/**
* Creates a new Conversation entity.
*
* #Route("/{id}", name="conversation_create")
* #Method("POST")
* #ParamConverter("advert", class="SkonsoftModelBundle:Advert")
* #Template("SkonsoftUserBundle:Conversation:new.html.twig")
*/
public function createAction(Request $request, Advert $advert)
{
$entity = new Conversation();
$entity->setAdvert($advert);
$form = $this->createCreateForm($entity);
$form->handleRequest($request);
$t = $this->get('translator');
if ($form->isValid()) {
$manager = $this->get('skonsoft_model.conversation_manager');
$manager->persist($entity);
$this->addFlash('success', $t->trans('message.send.success'));
return $this->redirect($request->headers->get('referer'));
}
$this->addFlash('danger', $t->trans('message.send.error'));
return array(
'entity' => $entity,
'form' => $form->createView(),
);
}
/**
* Creates a form to create a Conversation entity.
*
* #param Conversation $entity The entity
*
* #return \Symfony\Component\Form\Form The form
*/
private function createCreateForm(Conversation $entity)
{
$form = $this->createForm('ss_conversation', $entity);
return $form;
}
and this is the twig:
{{form_start(form, {'action': path('conversation_create', {'id': entity.advert.id}), 'method': 'POST', 'class':'form-horizontal', 'role':'form' } )}}
<div class="form-group row">
<div class="col-sm-12 col-xs-12">
{{ form_widget(form.message, {'attr': {'class': 'form-control pull-right', 'placeholder':"message.text_holder" | trans, 'rows':'6' } }) }}
</div>
<div class="widget_error col-sm-12 col-xs-12">
{{ form_errors(form.message) }}
</div>
</div>
<div class="form-group row">
<button type="submit" class="btn btn-success btn-lg {{'css.pull.right'|trans}}">{{ "Send" | trans }} </button>
</div>
{{form_end(form)}}
When i dump the FormView in the controller, i get the submitted data and their errors... but not in the wiew
Any Body has any idea what's wrong ?
Thank you

Answer 1

I'm sorry, it was my mistake, not related to symfony.
So, here is the problem:
With this configuration, everything works fine, just i used the render_esi helper to render the form and i forget that render_esi is a new request to make, so when i submit the form, first master request get and process the form, but i lose all form's data after calling the render_esi helper.
