TYPO3 Core

Hi,

i have a model called "Book" with a field lecturer that is lazy loaded:

    /**
     * @TYPO3\CMS\Extbase\Annotation\ORM\Lazy
     * @var \Varioous\VaTemplate\Domain\Model\Lecturer
     */
    protected $lecturer = null;

Then i want to update a Book B with the lecturer of Book a (via DataHandler -> proccessdatamapHook):

//not working
$book->setLecturer($parent->getLecturer());
$bookRepository->update($book);
$persistenceManager->persistAll();

if i load the lazy loaded instance, it works

if ($parent->getLecturer() instanceof LazyLoadingProxy) {
    $parent->getLecturer()->_loadRealInstance();
}

$book->setLecturer($parent->getLecturer());
$bookRepository->update($book);
$persistenceManager->persistAll();

Should be automatically handled by the update function of the Repository.
