Symfony version(s) affected: 4.4.20+
Description
Since bug #39659 was addressed in 4.4.20, a FormEvents::POST_SUBMIT listener was added to choice types with 'multiple' => true. This is causing the dynamic options that were added to be flagged as invalid and I cannot submit my form anymore. I am using JavaScript to dynamically add options which used to work just by calling:
public function buildForm(FormBuilderInterface $builder, array $options): void
{
// ...
$builder->get('my_field')->resetViewTransformers(); // allow dynamic options
}
But now I get
Symfony\Component\Form\Exception\TransformationFailedException {#2900 ▼
-invalidMessage: null
-invalidMessageParameters: []
#message: "The choices "choice1" do not exist in the choice list."
#code: 0
#file: "....vendor/symfony/form/Extension/Core/Type/ChoiceType.php"
#line: 186
trace: {▶}
}
How to reproduce
Use JavaScript to dynamically add an <option> to your ChoiceType field (select dropdown) and submit.
Additional context
I've been stuck at 4.4.19 for a while now because of this. I thought it might get addressed in future releases which is why I waited to submit this bug.
