creating form factory for file upload

i get the tracy error on the presenter although
this code works elsewhere

class LessonWizardStep3Presenter extends LessonWizardPresenter {
	/** @var \JDApp\Forms\LessonThreeFormFactory @inject */
	public \JDApp\Forms\LessonThreeFormFactory $formfactory3;

and

	protected function createComponentUploadPdfForm(): Form {
		//see details in /app/forms...
		$form = $this->formfactory3->create();
		return $form;
	}

the only diff between the other working form factories and this one is the use of the
file upload input type:

	<div class="struct"><input class="form-group" type="file" n:name="document"> Use PDF</div>

The business of onSubmit and onSuccess is best left to the Presenter or the Control.

Below an example of a Login form within a Control, it allows you to have some more specific events (such onAuthenticationSuccess) and it is more fine grained.

Factory:

final class LoginFormFactory
{
	public function create(): Form
    {
		$form = new Form;

		$form->addText('email', 'Email')
			->setRequired('Enter your email');

		$form->addPassword('password', 'Password')
			->setRequired('Enter your password');

		$form->addSubmit('submit', 'Login');

		return $form;
	}
}

Control:

use App\Forms\LoginFormFactory;

final class LoginControl extends Control
{
	private LoginFormFactory $loginFormFactory;

	private User $user;

	public $onAuthenticationSuccess = [];

	public function __construct(LoginFormFactory $loginFormFactory, User $user)
	{
		$this->loginFormFactory = $loginFormFactory;
		$this->user = $user;
	}


	protected function createComponentLoginForm(): Form
	{
		$form = $this->loginFormFactory->create();

		$form->onSuccess[] = [$this, 'doAuthentication'];

		return $form;
	}

	public function doAuthentication(Form $form, \stdClass $values): void
	{
		try {
			$this->user->login($values->email, $values->password);
		} catch (AuthenticationException $e) {
			$form->addError($e->getMessage());
			return;
		}
		Arrays::invoke($this->onAuthenticationSuccess);
	}
}

Presenter:

use App\Controls\LoginControl;
use App\Factories\LoginControlFactory;

final class UserPresenter extends Presenter
{
	private LoginControlFactory $loginControlFactory;

	public function __construct(LoginControlFactory $loginControlFactory)
	{
		parent::__construct();

		$this->loginControlFactory = $loginControlFactory;
	}

	protected function createComponentLogin(): LoginControl
	{
		$control = $this->loginControlFactory->create();

		$control->onAuthenticationSuccess[] = [$this, 'loginFormSucceeded'];

		return $control;
	}

	public function loginFormSucceeded()
	{
		$this->redirect('Homepage:default');
	}
}
