This issue is created automatically through a Github pull request on behalf of sandermarechal:

Url: #712

Message:

This is the cange requested by @stof and @beberlei in PR #710. It implements an extra lazy get on the working side of the relationship. As mentioned in #710 the unit tests fails for reasons I don't quite understand. The error I get is:

1) Doctrine\Tests\ORM\Functional\ExtraLazyCollectionTest::testGetIndexByManyToMany
Exception: [PHPUnit*Framework_Error*Notice] Undefined index: joinColumns

Trace:
/home/sander/src/doctrine2/lib/Doctrine/ORM/Persisters/BasicEntityPersister.php:1665

If someone with a little more understanding of the Doctrine internals can help me fix this, then we could restore some of the functionality that PR #710 had to remove.
