Form->addRule : Constants not working: What is my mistake? OR Docs not up-to-date?

1. This is my form in my HomepagePresenter:

namespace App\Presenters;
	use App\Model\PageFacade;
	use Nette;
	use Nette\Application\UI\Form;
	use Nette\Caching\Cache;
	use Nette\Utils\Arrays;
	...
	$form = new Form;
	$form->addText('form_name', 'Name*:')
		->setRequired('Dein Name')
		->setHtmlAttribute('placeholder', 'Dein Name')
		->addRule($form::Range, 'Mind. %d, max. %d Buchstaben', [2, 40])
		;
	$form->addSubmit('submit', 'Abschicken')
		->setOmitted();

According to https://doc.nette.org/…in-presenter#… :
(copied from the doc)

$form->addInteger('age', 'Age:')
	->addRule($form::Range, 'You must be older 18 years and be under 120.', [18, 120]);

$form->addPassword('password', 'Password:')
	->setRequired('Pick a password')
	->addRule($form::MinLength, 'Your password has to be at least %d long', 8);

2. This is the result – given by Tracy:

“Undefined constant Nette\Application\UI\Form::Range”

The same with other constants like MinLength, MaxLength, Pattern.

According to https://doc.nette.org/…s/validation#…
and https://api.nette.org/…ms/Form.html
these constants should work (?)

3. When I do it this way, it works!

	$form = new Form;
	$form->addText('form_name', 'Name*:')
		->setRequired('Dein Name')
		->setHtmlAttribute('placeholder', 'Dein Name')
		->setHtmlAttribute('autocomplete', 'on')
		->addRule($form::RANGE, 'Mind. %d, max. %d Buchstaben', [2, 40])
		->addRule($form::PATTERN, 'Einen normalen Namen, bitte', '([a-zA-Z]{2,})([-a-zA-Z\.\s]*)')
		;

4. This my actual composer.json

Hi, you need to select correct version in the docs, for some reason 4.0 is default, 3.x is here https://doc.nette.org/…lidation/3.x.

You must use constants with uppercases, like $form::RANGE, $form::PATTERN etc.

Constants as PascalCase are defined in Nette\Forms 4.0, that is not fully released, but documentation is ready for that. It is reason, why 3rd point is fully works.

Then it's clear.. Thanks a lot!
