Description
Hello UX-Team,
first off, thank you for this initiative - developing frontends with symfony is actually fun again.
I am uncertain whether this is an issue relevant for this repo, but here goes:
I want to test form submits of a LiveComponent with the "ComponentWithFormTrait".
The Component:
#[LiveProp(writable: true)]
public ?FormModel $initialFormData = null;
protected function instantiateForm(): FormInterface
{
$this->initialFormData = $this->initialFormData ?? new FormModel();
return $this->createForm(FormType::class, $this->initialFormData);
}
#[LiveAction]
public function save(): Response
{
$this->submitForm();
return new Response('success');
}The FormType:
class FormType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('password', RepeatedType::class, [
'label' => 'Password',
'type' => PasswordType::class,
'options' => ['always_empty' => false]
]);
}
}The FormModel:
class FormModel
{
#[NotBlank]
public ?string $password = null;
}Now the TestCase is pretty simple as well:
use InteractsWithLiveComponents;
public function testFormComponent(): void
{
// instantiate model with valid value
$model = new FormModel();
$model->password = 'some_password';
$testComponent = $this->createLiveComponent(FormComponent::class, ['initialFormData' => $model]);
/** @var FormComponent $component */
$component = $testComponent->component();
try {
$response = $component->save();
} catch (Throwable $e) {
self::assertFalse('Did not expect component to fail with message: '.$e->getMessage());
}
}Invoking the "save()" function always yields a validation error, because the Component does not correctly populate the "initialFormData" property.
Creating the Component with "createLiveComponent" and retrieving it with "component()" works as expected - the model contains the "password" property and the FormView is set accordingly.
But when invoking the "save()" function, the models "password" property is suddenly set to "null".
Changing the FormType to use a "TextType" instead of "PasswordType" works, the "password" property is not reset - however the "always_empty" property is set to false in the FormType-builder, so that should not be an issue...
Whether this is more of a Symfony/Form or a PIBKAC issue I dont know...but maybe someone knows whats going on.
I created a small reproducer here
It runs within a docker compose environment, for convenience. Just run "bin/phpunit". I added a few dump() statements to emphasize relevant parts.
