Doctrine 2 under Zend error: Class Entities\X has no association named Entities\Y - zend-framework

Question

I have a rather strange problem. I'm using Doctrine 2 under Zend Framework 1.11. I have a database called "Sessions", which are training sessions for students. Each session has an associated note, called a SOAPE note. Edit: I am now including both of the entities in question.
Sessions:

When calling $em->getRepository('Entities\Sessions')->findOneBy('id'), everything works fine--I get the session and its accompanying SOAPE note. Ditto for other associated tables' data.
But now I am trying to write a custom repository to get the notes prior to this session. The function is as follows:
<?php
namespace Repositories;
use Doctrine\ORM\EntityRepository;
use Doctrine\ORM\Query\ResultSetMapping;
use Doctrine\DBAL\Types\Type;
/**
* Sessions
*/
class Sessions extends EntityRepository
{
public function getPastSoapeNotes($params) {
$studentId = $params['studentId'];
$latestSession = $params['snDatetime'] ?: date('Y-m-d H:i');
$qb = $this->_em->createQueryBuilder();
$qb->select('n.subjective, n.objective, n.plan, n.action, n.education')
->from('Entities\Sessions', 'sn')
->innerJoin('sn.Entities\SnSoapeNotes', 'n');
return $qb->getQuery()->getResult();
}
}
When I call this, I get the following error:
[Semantical Error] line 0, col 126 near 'n': Error: Class Entities\Sessions has no association named Entities\SnSoapeNotes
I have also tried using the "mappedBy" and "inersedBy" annotations in every possible combination, but to no avail; Doctrine can't seem to find the association. I am at a complete loss as to what is going on.

Answer 1

I figured out what I did wrong. In the join statement, I used 'sn.Entities\SnSoapeNotes' when I should have used just 'soapeNote', which is the property in the Sessions class, not the table name itself.
