[TYPO3-mvc] Persist objects after adding or updating

[Dirk Wenzel]

Hi all,
is it necessary to persist extbase objects manually after adding or 
updating them?

In ObjectController:

createAction($object) {
  $object->setValue('foo');
  $this->objectRepository->add($object);

?>> $this->persistenceManager->persistAll();
  $this->redirect('show' ...)
}

updateAction($object) {
  $object->setValue('foo');
  $this->objectRepository->update($object);

?>> $this->persistenceManager->persistAll();
  $this->redirect('show' ...)
}

I do not need to access any (updated) property after adding/updating in 
this actions.

Thank you for any advice!
Dirk
