Setting parent document to a Generic Node created on-the-fly in a prePersist listener causes PHPCRException

[kminh]

Hello,

I'm trying to "move" a new (yes a new) document (Symfony\Cmf\Bundle\RoutingBundle\Doctrine\Phpcr\Route) to another node by using setParentDocument in a prePersist event listener.

The target node is created on the fly if it's not there, using NodeHelper::createPath (I only need a generic target node).

    public function prePersist(LifecycleEventArgs $args)
    {
        $route = $args->getObject();
        $dm = $args->getObjectManager();

        if ($route instanceof Route) {
            $localeNodePath = $this->routeRoot . '/' . $this->locale;

            if (!$localeNode = $dm->find(null, $localeNodePath)) {
                $session = $dm->getPhpcrSession();
                $localeNode = NodeHelper::createPath($session, $localeNodePath);

                /* $session->save(); I believe this is not needed? */ 
            }

            $route->setParentDocument($localeNode);
        }
    }

The exception message is Document is not managed and has no id ....

Perhaps this is caused by the fact that the target node is created on the fly, but even calling $session->save doesn't help.

Any insight is greatly appreciated.

can you try and create a test case for this?

Hmm not sure where I should place the test? Here perhaps?

I don't know anything about PHPCR ODM's internals so I'm not sure if I can create something useful.

have a look at some of the event tests here for inspiration https://github.com/doctrine/phpcr-odm/tree/master/tests/Doctrine/Tests/ODM/PHPCR/Functional
