[Form] Custom Form Type with the same name as its parent Symfony form type results in exception upon rednering #58825
Description
Symfony version(s) affected
7.1.7
Description
What I do:
I create a custom form type for an emali field, which has a name colliding with a Symfony's form type, as following:
<?php
namespace App\Form\User;
use Symfony\Component\Form\Extension\Core\Type\EmailType as BaseEmailType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\OptionsResolver\OptionsResolver;
class EmailType extends AbstractType
{
public function configureOptions(OptionsResolver $resolver): void
{
$resolver->setDefaults([
// ... defaults are set here
]);
}
public function getParent(): string
{
return BaseEmailType::class;
}
}What I expect:
The form is rendered to the end user.
What I get:
An exception rendered to the end user:
An exception has been thrown during the rendering of a template ("Unable to render the form because the block names array contains duplicates: "_sign_up_email_row", "email_row", "email_row", "text_row", "form_row".").
Experiment:
If I change my form type class name from EmailType to anything else, e.g. MailType, the form is rendered successfully
