Bug Report

Q	A
BC Break	yes
Version	3.0-dev

Summary

Using Redis cache causes an error when getting proxies for entities with an inherited id or inherited transient property.

Current behavior

The second time a proxy class is requested after its initial generation will cause the following error:
"Call to a member function getProperty() on null in Doctrine/ORM/Proxy/Factory/StaticProxyFactory.php:190"

How to reproduce

Configure Doctrine with Redis cache.
Create entities like this:

<?php
use Doctrine\ORM\Annotation as ORM;
/** @ORM\MappedSuperclass */
class Item {
    /** @ORM\Id @ORM\Column */
    protected $id;
}
/** @ORM\Entity */
class Child extends Item {}

Run doctrine orm:generate-proxies, or anything else that will get the proxy classes.
Repeat step 3 a second time.

Expected behavior

No error.

Additional information

This issue does not happen on v2.7, or if using Memcached instead.
There's a comment at the line causing the error that says "TODO possible NPE".

@andrews05 Does this happen because Child itself doesn't have the annotations despite that a mapped superclass is used?

@SenseException you mean the id annotation? I don’t think you’re allowed to re-declare a field in a subclass, doctrine will complain.
My actual use case is with JTI, where the id is necessarily inherited.
