Incorrect form fields configuration about form

[rustamwin]

@terabytesoftw I meant this test:

Yiisoft\Form\Tests\Widget\NoExistTest::test Undefined property: Yiisoft\Form\Tests\Stub\PersonalForm::$undefined_form_attribute

as you said above.

Of course you are just creating the object, you are not rendering it.

(new TextInput)->config($data, 'undefined_form_attribute')->run();

TextInput::widget()->config($data, 'undefined_form_attribute')->run();

<?= (new TextInput)->config($data, 'undefined_form_attribute') ?>

<?= TextInput::widget()->config($data, 'undefined_form_attribute') ?>

1. Yiisoft\Form\Tests\Widget\NoExistTest::test Undefined property: Yiisoft\Form\Tests\Stub\PersonalForm::$undefined_form_attribute

Please reopen issue. In your described cases widget still no throws exception for undefined field

class LoginForm extends FormModel {
    private ?string $login;
    private ?string $password;
    /* ...  */
}

echo (new TextInput)->config($formModel, 'login')->run();
echo (new PasswordInput)->config($formModel, 'password')->run();
echo (new TextInput)->config($formModel, 'undefined_form_attribute')->run();

in html i got this

<input type="text" id="login" name="login">
<input type="password" id="password" name="password">
<input type="text" id="undefined_form_attribute" name="undefined_form_attribute">

You can put all the code to reproduce the error clearly you must have some problem in your php configuration, I already added the exception but it is redundant all the widgets use getAttributeValue(), and when looking to return the value of the property it should throw the error because it does not exists.

I still wonder why it does not generate the error, if it is tested.

@rustamwin We must verify well, I think it is not a bug.

I don't need to test the widget because it is clearly tested in the FormModel.

Any object that calls a property that doesn't exist php will return an error.
