[TYPO3-english] Form Framework in Extension: Custom Finisher in relation to record

[Mikel]

I’m responsing to myself for possible other readers:

Solution 1 = Custom Finisher implementation:

In my case I added a new finisher, extending the mailfinisher.
Short summary:

class MailToContactPersonFinisher extends EmailFinisher
{
    const FORMAT_PLAINTEXT = 'plaintext';
    const FORMAT_HTML = 'html';

    /**
     * @var array
     */
    protected $defaultOptions = [
        'recipientName' => '',
        'senderName' => '',
        'format' => self::FORMAT_HTML,
        'attachUploads' => true
    ];

    /**
     * Executes this finisher
     * @see AbstractFinisher::execute()
     *
     * @throws FinisherException
     */
    protected function executeInternal()
    {

       /** @var FormRuntime $formRuntime */
       $formRuntime = $this->finisherContext->getFormRuntime();
       $standaloneView = $this->initializeStandaloneView($formRuntime);

       if ($formRuntime->getResponse()->getRequest()->hasArgument('contactPerson')) {
          $id = $formRuntime->getResponse()->getRequest()->getArgument('contactPerson');

          $objectManager = GeneralUtility::makeInstance(ObjectManager::class);
          /** @var ContactPersonRepository $repository */
          $repository = $objectManager->get(ContactPersonRepository::class);
          /** @var ContactPerson $contactPerson */
          $contactPerson = $repository->findByUid($id);

          $this->setOption('subject', 'FOOBAR');
          $this->setOption('recipientAddress', $contactPerson->getEmail());
          $this->setOption('senderAddress', $formRuntime->getRequest()->getArgument('email'));
          $this->setOption('senderName', $formRuntime->getRequest()->getArgument('name'));
           parent::executeInternal();


       }


    }

}

Solution 2 = Loading and manipulating the yaml configuration and build the form:

/** @var FormPersistenceManagerInterface $formPersistanceManager */
$formPersistanceManager = $this->objectManager->get(FormPersistenceManagerInterface::class);
$formConfiguration = $formPersistanceManager->load('EXT:path_to_ext/Resources/Private/Forms/NameOfForm.yaml');
$formDefinition->createFinisher(
 'EmailToReceiver',
 [
  'subject' => 'Dies ist meine Mail',
  'recipientAddress' => $contactPerson->getEmail(),
  'recipientName' => $contactPerson->getName(),
  'senderAddress' => 'mail at example.xy',
  'senderName' => 'Max Mustermann',
 ]
);
/** @var FormRuntime $form */
$form = $formDefinition->bind($this->request, $this->response);
$this->view->assign('form', $form->render());

In my use case solution 1 was perfect. Solution 2 is in my opinion more like a workaround, a bit more complicated, but allows more manipulation and customization. 
With a custom finisher, I did not have the chance to influence other finishers. For example, if the form factory has other mail finishers, I can’t interrupt sending them all. Or is there a way to stop all other finishers from a single finisher? Something like $this->finisherContext->getFormRuntime()->stopFinisherPropgation(); ?
