I have a entity with a price property in a form. In a update i want cancel the changes for this entity.

This is my code in preUpdate event listener:

if($entityManager->contains($entity)) {
    $entityManager->detach($entity);
    $uow  = $entityManager->getUnitOfWork();
    $meta = $entityManager->getClassMetadata(get_class($entity));
    $uow->recomputeSingleEntityChangeSet($meta, $entity);
}

But in a test a get this error message:

1) WebFactory\PriceListBundle\Tests\Entity\PriceListTest::testCreateProduct Doctrine\ORM\ORMInvalidArgumentException: Entity WebFactory\Bundle\PriceListBundle\Entity\PriceList@000000005f6fc4da0000000028ff97b1 is not managed. An entity is managed if its fetched from the database or registered as new through EntityManager#persist
