Old options will remain

[ukeloop]

If I want to change rules and the number of rules is too small, the old rules will remain.

$form = $this->plain()
    ->add(
        'email',
        'email',
        [
            'rules' => [
                'rule_a',
                'rule_b',
                'rule_c',
            ],
        ],
    );

$form->modify(
    'email',
    'email',
    [
        'rules' => [
            'rule_d',
        ],
    ],
);

Modified rules is

$form->email->getOption('rules');
// [
//     'rule_d',
//     'rule_b',
//     'rule_c',
// ],

But I expect

$form->email->getOption('rules');
// [
//     'rule_d',
// ],

It seems that was intentional..? Kinda? See #577 - I'm lost...

I had missed out on that PR. Thanks for letting me know.

However, I think this problem applies to all options of type list, such as choice.

I'm just as eager to make this project better as you are.

Thank.

We need a few rewrites. No more ParentType (choice) for select/radios/checkboxes, better options merging, better collection value/models, fixing the form field, probably more, lots of BC breaks.
