public function ZoneDefaultWidget::errorElement in Address 8

Assigns a field-level validation error to the right widget sub-element.

Depending on the widget's internal structure, a field-level validation error needs to be flagged on the right sub-element.

Parameters

array $element: An array containing the form element for the widget, as generated by formElement().

\Symfony\Component\Validator\ConstraintViolationInterface $violation: A constraint violation reported during the validation phase.

array $form: The form structure where field elements are attached to. This might be a full form structure, or a sub-element of a larger form.

\Drupal\Core\Form\FormStateInterface $form_state: The current state of the form.

Return value

array|bool The element on which the error should be flagged, or FALSE to completely ignore the violation (use with care!).
