Form is not anchored and therefore can not determine whether it was submitted.

Hello, i am using your hack to work with NasExt/DependentSelectBox (it was sloved here https://github.com/WebChemistry/forms-multiplier/issues/12 ), but with latest version i am getting this error again: Form is not anchored and therefore can not determine whether it was submitted. So probably its something broken. Can you help me please? The hack is this code:

$signalName = $this->getUniqueId() . '-' . $name . '-' . $groups->getName();
if (is_array($this->getPresenter()->getSignal()) && $this->getPresenter()->getSignal()[1] === 'load' && preg_match('#' . $signalName . '-([0-9]+)#', $this->getPresenter()->getSignal()[0], $matches)) {
    $groups->addCopy($matches[1]);
}
