Can't use addConditionOn() when creating Multiplier

[foxycode]

Code:

$disks = $form->addMultiplier('disks', [$this, 'addDisk'], 0);

public function addDisk(Container $container): void
{
    $container->addText('size', 'Size')
        ->addConditionOn($container->form['brand'], Form::EQUAL, 'kvm')
            ->setRequired();
}

Error:

Nette\InvalidStateException
Component '' is not attached to 'Nette\Forms\Form'.

You can try this:

$disks = $form->addMultiplier('disks', [$this, 'addDisk'], 0);

public function addDisk(Container $container, Form $form): void
{
    $container->addText('size', 'Size')
        ->addConditionOn($form['brand'], Form::EQUAL, 'kvm')
            ->setRequired();
}

@MartkCz Great, it's working :) Maybe this should be in docs. I have feeling that I dealt with this earlier.
