---> action (ref to controller)
It is mapped with inheritamce type = "JOINED"
During the class ClassMetadata deserialization exception belows is thrown:

ReflectionException: Property id does not exist in E:\Projects\portal\library\Doctrine\ORM\Mapping\ClassMetadata.php on line 362

I have found workaround:

  1. add to returned by the *_sleep method array 'reflClass' and 'reflFields' fields.
  2. write code for recreating the ReflectionClass and ReflectionPropery objects (I think this is a PHP error, Reflection_ classes is restored in wrong state). It looks like code below:
        $this->reflClass = new \ReflectionClass($this->reflClass->name);
        foreach ($this->reflFields as $field => $reflField) {
            $this->reflFields[$field] = new \ReflectionProperty($reflField->class, $reflField->name);
            $this->reflFields[$field]->setAccessible(true);
        }

The issue seems to be that ReflectionClass::getProperty() will only return properties that are defined directly by the class. The attached patch seems to resolve the issue for me.

Thanks for the patch but I think there is a better (faster) way to resolve this as we know when a field stems from a superclass and the name of that class.

I will commit a patch soon.
