Same name and namespace in other branches

1. 2.0.x src/Entity/Form/GroupContentForm.php \Drupal\group\Entity\Form\GroupContentForm::complete()

Completes the creation wizard by saving the target entity.

Please note that we are instantiating an entity form to replicate the first step and call the save method on that form. This is done to ensure that any logic in the save handler is actually run when the wizard completes.

Parameters

array $form: An associative array containing the structure of the form.

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