Description
After updating Symfony 4.4.19 to 4.4.20,
some forms using Entitytype class - populated with json - give the following error when handling request :
The value array is not valid. | recipients | Caused by:
Symfony\Component\Form\Exception\TransformationFailedException {#6790 ▼

It works perfectly with SF 4.4.19.

How to reproduce
- Juste create a simple form with an empty choice list:
$form = $this->createFormBuilder()
->add('recipients', EntityType::class, [
'class' => MyEntity::class,
'translation_domain' => 'mytranslation_domain',
'choice_label' => 'choice_label',
'label' => 'em.texts.to',
'multiple' => true,
'mapped' => true,
'choices' => $mychoices
]);-
print in a twig using select2 lib
-
populate with a json request, make a choice and submit
Possible Solution
Patching src/Symfony/Component/Form/Extension/Core/Type/ChoiceType.php ?
