Getting user input data in FormEvents::SUBMIT - forms

Question

I am looking for a way to get user data in the formEvents::SUBMIT event.
I can get it in formEvents::PRE_SUBMIT using
$builder->addEventListener(FormEvents::PRE_SUBMIT, function() {
//...
$userInput = $event->getData());
//...
});
I can get it in formEvents::POST_SUBMIT using
$builder->addEventListener(FormEvents::POST_SUBMIT, function() {
//...
$userInput = $event->getForm()->getViewData()
//...
});
But in formEvents::SUBMIT I cannot find where, though I read it can be accessed:
Symfony2: dynamic generation of embedded form
I can find other project getting data using the same method as PRE_SUBMIT, for instance here:
https://github.com/Klerik/web-dersen/blob/65ba1bafa574dc2bda6dd2bb738fe0d33a06bf71/src/Catalog/FilmsBundle/Form/EventListener/UploadFileSubscriber.php
or there:
https://github.com/alexandresalome/bros/blob/59c111eb481c2fd672f3646390455ddad65dd800/src/Bros/ServerBundle/Form/Type/BrowserType.php
Though in my situation I test with user input that does not fit the Normalisation - $event->getForm()['field']->getData() sends an object without the user data which have been refused.
Still I want to retrieve user input to:
* change accordingly (testing data validity) my current form (which cannot be done in POST_SUBMIT),
* use my form related object (not available in PRE_SUBMIT)
EDIT
Here are the relevant parts of the ...Type Class :
public function buildForm(FormBuilderInterface $builder, Array $options)
{
$adminUserQuery = $options['admin_user_query'];
$builder
->add('admin_user', 'model', Array( //using Propel as ORM
'label' => FALSE,
'multiple' => FALSE,
'expanded' => FALSE,
'class' => 'App\\CoreBundle\\Model\\AdminUser',
'query' => $adminUserQuery,
'empty_value' => 'form.placeholder.admin_user',
'property' => 'email',
));
//...
$builder->addEventListener(
FormEvents::PRE_SUBMIT, function (FormEvent $formEvent)
{
var_dump($formEvent->getData(), '---'); // prints: array(1) { ["admin_user"]=> string(17) "test#email.test" }
var_dump($formEvent->getData()['admin_user'], '---'); // prints: string(15) "test#email.test"
//...
});
$builder->addEventListener(
FormEvents::SUBMIT, function (FormEvent $formEvent)
{
var_dump($formEvent->getData()); // prints: object(App\CoreBundle\Model\EventUserRole)#1659 {...}
var_dump($formEvent->getData()->getAdminUser()); // prints: NULL
//...
}
);
}
Anyone ?

In the FormEvents::Submit action, you can do this (assuming you are editing a User):
$builder->addEventListener(FormEvents::SUBMIT, function ($event) {
// Your Entity/Document
$user = $event->getData();
// Grab the actual form
$form = $event->getForm();
// ...
});
