Adding additional persist calls to preUpdate call in Symfony 2.1

The key is to persist them after the flush:

<?phpnamespace Comakai\CQZBundle\Handler;use Symfony\Component\DependencyInjection\ContainerInterface;use Doctrine\Common\EventSubscriber;use Doctrine\ORM\Event;/** *  */class YourHandler implements EventSubscriber{    protected $things = [];    public function getSubscribedEvents()    {        /**         * @todo Check if this is running in the console or what...         */        if (isset($_SERVER['HTTP_HOST'])) {            return [                'preUpdate',                'postFlush'            ];        }        return [];    }    public function preUpdate(Event\LifecycleEventArgs $eventArgs)    {        $em = $eventArgs->getEntityManager();        $uow = $em->getUnitOfWork();        $entity = $eventArgs->getEntity();        $updateArray = $eventArgs->getEntityChangeSet();        //Updates        if (($entity instanceof Bam) === false) {            $thing = new OtherThing();            $thing->setFoo('bar');            $this->things[] = $thing;        }    }    public function postFlush(Event\PostFlushEventArgs $event)    {        if(!empty($this->things)) {            $em = $event->getEntityManager();            foreach ($this->things as $thing) {                $em->persist($thing);            }            $this->things = [];            $em->flush();        }    }}
