I have a self referencing entity with parent and children. The strange thing is, when I add the form elements (DoctrineModule ObjectSelect) for parent and children to the form, some other fields of the parent entity doesn't update, when I persist the entity. The child entities are updating fine.
In the update query of the parent aren't these fields which I want to update. It's like doctrine doesn't recognize the changes for the parent (owning side) anymore. Before the persist I get the right entity with the actual changes from the form, but than doctrine doesn't update the changed fields in the query.
When I delete the form elements for parent and children in the form, everything works fine and the parent entity update/persist all fields.

Answer based (and might still change) based on discussion in comments with OP under question.
Simple use case: self-referencing Doctrine Entity does not correctly update parent/child related Entity object properties on on-save action.
OP provided Entity.
I'm assuming you have a Form setup for this Entity. I'm also assuming it's correctly setup, as you did not provide it after being asked (because, rightly so, it would mean a lot of code). However, assuming stuff with code makes for a lot of mistakes, which is why I mention it here.
As such, I'm assuming the handling of your Form in the Controller might be faulty. To check, please use the following simplified addAction
function and give it a shot (Factory code below).
/**
* @var RentalForm
*/
protected $form;
/**
* @var ObjectManager
*/
protected $objectManager;
public function __construct(ObjectManager $objectManager, RentalForm $form)
{
$this->form = $form;
$this->objectManager = $objectManager;
}
public function addAction()
{
/** @var RentalForm $form */
$form = $this->getForm();
/** @var Request $request */
$request = $this->getRequest();
if ($request->isPost()) {
$form->setData($request->getPost());
if ($form->isValid()) {
$entity = $form->getObject();
$this->getObjectManager()->persist($entity);
try {
$this->getObjectManager()->flush();
} catch (\Exception $e) {
$message = sprintf(
'Was unable to save the data. Saving threw an error. <br />Code: %s. <br />Message: %s',
$e->getCode(),
$e->getMessage()
);
$this->flashMessenger()->addErrorMessage($message);
return [
'form' => $form,
'validationMessages' => $form->getMessages() ?: '',
];
}
$this->flashMessenger()->addSuccessMessage(
$this->getTranslator()->translate('Successfully created object.')
);
// TODO replace vars with your own: return $this->redirect()->route($route, $routeParams);
}
$this->flashMessenger()->addWarningMessage(
'Your form contains errors. Please correct them and try again.'
);
}
return [
'form' => $form,
'validationMessages' => $form->getMessages() ?: '',
];
}
Factory for class with the above, modify as needed for you situation
class RentalControllerFactory implements FactoryInterface
{
public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
{
/** @var ObjectManager $objectManager */
$objectManager = $container->get(EntityManager::class);
/** @var FormElementManagerV3Polyfill $formElementManager */
$formElementManager = $container->get('FormElementManager');
/** @var RentalForm $form */
$form = $formElementManager->get(RentalForm::class);
return new RentalController($objectManager, $form);
}
}
