Compiler pass - resolve target entity doesn't load - doctrine-orm

Question

I'm working on a bundle and i need to load a doctrine resolve_target_entities from a configuration parameter.
This article should be my solution, the fact is that using the bundle it seems not to load the "compiler pass class".
This is my bundle class
class PersonalBundle extends Bundle
{
public function build(ContainerBuilder $container){
parent::build($container);
$container->addCompilerPass(new ResolveTargetEntitiesPass());
}
}
This is the ResolveTargetEntitiesPass class
class ResolveTargetEntitiesPass implements CompilerPassInterface
{
/**
* {#inheritdoc}
*/
public function process(ContainerBuilder $container)
{
// Gets the custom entity defined by the user (or the default one)
$customEntityClass = $container->getParameter('personal.custom_class');
// Skip the resolve_target_entities part if user has not defined a different entity
if (DefaultClassInterface::DEFAULT_ENTITY_CLASS == $customEntityClass) {
return;
}
// Throws exception if the class isn't found
if (!class_exists($customEntityClass)) {
throw new ClassNotFoundException(sprintf("Can't find class %s ", $customEntityClass));
}
// Get the doctrine ResolveTargetEntityListener
$def = $container->findDefinition('doctrine.orm.listeners.resolve_target_entity');
// Adds the resolve_target_enitity parameter
$def->addMethodCall('addResolveTargetEntity', array(
DefaultClassInterface::DEFAULT_ENTITY_CLASS, $customEntityClass, array()
));
// This was added due this problem
// https://stackoverflow.com/a/46656413/7070573
if (version_compare(Version::VERSION, '2.5.0-DEV') < 0 && !$def->hasTag('doctrine.event_listener')) {
$def->addTag('doctrine.event_listener', array('event' => 'loadClassMetadata'));
} elseif (!$def->hasTag('doctrine.event_subscriber')) {
$def->addTag('doctrine.event_subscriber');
}
}
}
When i use the class it raises this error
Expected value of type "PersonalBundle\Entity\DefaultClass"
for association field "PersonalBundle\Entity\Group#$defaultClass", got
"App\Entity\CustomClass" instead.
As i said it seems not to load the ResolveTargetEntitiesPass...
Thanks

Answer 1

So i solved the problem changing the priority of the compiler pass.
I've tried to move the bundle on top in config/bundle.php and it started working, then following this https://symfony.com/blog/new-in-symfony-3-2-compiler-passes-improvements i've left the default type but increased the priority (from 0, default, to 1).
I'm not sure which service has been "downgraded" so if anyone has an idea it's welcome.
<?php
// ...
use Symfony\Component\DependencyInjection\Compiler\PassConfig;
class PersonalBundle extends Bundle
{
public function build(ContainerBuilder $container){
parent::build($container);
$container->addCompilerPass(new ResolveTargetEntitiesPass(), PassConfig::TYPE_BEFORE_OPTIMIZATION, 1);
}
}
