False positive with Symfony Forms about phpstan-symfony HOT 6 OPEN

Actually it wasn't, I completely screwed that up. @aturki can you show me what parameters (especially the first one) are you calling createForm with, your FormType class, and anything else you feel I could need? Thanks.

Hi @lookyman, createForm is called as:
$this->createFormat(DocumentType::class, $entity, $parameters);

Note the DocumentType is a subclass of the Symfony standard Symfony\Component\Form\AbstractType

Let me know if you need extra infos ;)

I think it's no false positive, but something ugly in the Form component:

The FormInterface returned by the builder does not include the getClickedButton() method which is part of the Form class. So phpstan would have to inspect the returned form object.

I opened a ticket for this at Symfony, see symfony/symfony#35277

from phpstan-symfony.

For now, the solution is to add a PHPDoc - see symfony/symfony#35277 (comment) :

use Symfony\Component\Form\Form;

/** @var Form $form */
$button = $form->getClickedButton();
