After an update of some Symfony 2 bundles I suddenly got this error spl_object_hash() expects parameter 1 to be object, null given. It has happened before though everytime it is quite an adventure to debug this.
It happens the moment $em->persist($ra) is invoked only when the type of the $entity is Bla\OrmBundle\Entity\TapApplianceComponent. To me the values the $ra object is containing look valid.
Any ideas?
$ra->getLocation()->addComponent($entity);
$entity->setLocation($ra->getLocation());
switch (get_class($entity)) {
case 'Bla\OrmBundle\Entity\TapApplianceComponent':
$ra->getTapsAndAppliances()->addTapApplianceComponent($entity);
$entity->setTapsAndAppliances($ra->getTapsAndAppliances());
break;
default:
}
$em->persist($ra);
$em->persist($entity);
$em->flush();
I got a stacktrace like bellow:
exception 'PHPUnit_Framework_Error_Warning' with message 'spl_object_hash() expects parameter 1 to be object, null given' in C:\xampp\htdocs\TestServer\vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php:1602
