BC Break Report

Q	A
BC Break	I guess yes
Version	2.11.0

Summary

Persisting versioned entities in a class table inheritance scenario fails with LengthException. Migration notes do not mention any changes regarding versioned entities.

Previous behavior

Persisting such entities worked fine in 2.10.3 (previous version I used).

Current behavior

Persisting versioned entities in a class table inheritance scenario fails with LengthException. I think this is related to commit e369cb6e73 which introduced generated/virtual properties and requires version column to provide a value before initially flushing the newly created entity in JoinedSubclassPersister.php.

Simply moving assignDefaultVersionAndUpsertableValues() AFTER the insertion of the joined subclass fixes the issue.

I'll try to provide a PR asap.

How to reproduce

Try persisting a versioned entity in a class table inheritance scenario.

Example

/**
 * @ORM\Entity()
 * @ORM\InheritanceType("JOINED")
 * @ORM\DiscriminatorColumn(name="type", type="string")
 * @ORM\DiscriminatorTable({
 *     "user_group_contract" = "UserGroupContract"
 * })
 */
abstract class SubjectOfElection {

    /**
     * @ORM\Column(type="guid")
     * @ORM\Id()
     */
    private string $id;

}

/**
 * @ORM\Entity()
 */
class UserGroupContract extends SubjectOfElection {
    /**
     * @ORM\Column(type="integer")
     * @ORM\Version()
     */
    private int $version;
}
