[bug] cancelOnFail not working properly since 3.0.4

[Frost007]

Expected And Actual Behavior

I try to add validation to a form field with "cancelOnFail" attribute.
In 3.0.0 it worked as expected. it stopped the field's validation it self, but in 3.0.4 somehow it stops the whole validation. So i don't get any validation messages from the fields that are placed after the field that has cancelOnFail.

My field validation looks like this.

        $element = new Text('lastName');
        $element->setLabel('user.lastName');
        $element->setFilters([
            "string",
            "striptags",
            "trim",
        ]);
        $element->addValidators([
            new PresenceOf([
                'message'        => 'user.lastName.presenceOf'
                , 'cancelOnFail' => true
            ])
            , new StringLength([
                'min'               => 3,
                'max'               => 255,
                'messageMaximum'    => 'user.lastName.max',
                'messageMinimum'    => 'user.lastName.min'
            ])
        ]);
        $this->add($element);

        $element = new Text('firstName');
        $element->setLabel('user.firstName');
        $element->setFilters([
            "string",
            "striptags",
            "trim",
        ]);
        $element->addValidators([
            new PresenceOf([
                'message'        => 'user.firstName.presenceOf'
                , 'cancelOnFail' => true
            ])
            , new StringLength([
                'min'               => 3,
                'max'               => 255,
                'messageMaximum'    => 'user.firstName.max',
                'messageMinimum'    => 'user.firstName.min'
            ])
        ]);
        $this->add($element);

Lets say i only have these two field in the form. If i don't fill any of them, i should get 2 PresenceOf validation messages. One for 'firstName' and one for 'lastName'. But it's not the case i only get one message for 'lastName' and the cancelOnFail stop the whole validation.

Could you guys provide a minimal script, with which I would reproduce the error.

[Frost007]

For example Auth controller has an index action where the user can log in.

public function indexAction(){
        
        $form = new LoginForm();

        if ($this->request->isPost() && $form->isValid($this->request->getPost())) {
       
        }

       $this->view->form = $form;
}

In the auth/index.phtml file:

<form method="post" action="">

    <?php $form->renderDecorated(); ?>

    <input type="submit" value="login">

</form>

The form could be the one that i wrote above. If you leave both of the fields empty than the validation fails and you get the first field validated not both.

@Frost007 Did you see #13167

[Frost007]

Yes, i saw that. what exactly dou you want me to provide?

[sergeyklay]

As you can see the test passed. All works as expected. Could you please create a PR with test which will failed?

[sergeyklay]

I'm closing this issue due to the lack of any reaction. I'll open it again if the need arises

[marcojetson]

test expectation is wrong, issue creator says he is expecting 2 PresenceOf, one for firstName and one for lastName

before 3.0.3 Form::isValid() was running Validation::validate() one element at a time so cancelOnFail was cancelling the validators per element
since 3.0.3 this behaviour changed since Form::isValid() runs the validation once for all fields

[laffentaller]

@sergeyklay : aggree with @marcojetson we should get two 'PresenceOf' messages in case firstName and lastName both leaved empty.

[sergeyklay]

@laffentaller Could you please create a PR with failed tests? Feel free use #13167 as example
