Sending non array causes UnexpectedTypeException #13804
Description
Hi guys,
I just notice that, when I send a non array data to a collection form field the ResizeFormListener throws an UnexpectedTypeException before the form validation.
Here is the action
public function indexAction(Request $request)
{
$form = $this->get('form.factory')->createNamed('', new FooType, null, [
'method' => 'GET'
]);
$request->query->set('emails', 'a');
// Throws an exception
$form->handleRequest($request);
if ($form->isValid()) {
die(var_dump('valid'));
}
die(var_dump($form->getErrorsAsString()));
}
And the form
class FooType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('emails', 'collection', [
'type' => 'email'
]);
}
public function getName()
{
return 'foo';
}
}
Is there anything that I can do to avoid this? By this I mean to get a non valid form instead of an Exception...
I don't really get why https://github.com/symfony/symfony/blob/2.7/src/Symfony/Component/Form/Extension/Core/EventListener/ResizeFormListener.php#L147 should throws an Exception instead of doing a $data = []; or something.
What do you think?
