Facing "Undefined index: (fieldname) in Doctrine/ODM/MongoDB/UnitOfWork.php line 736"

[vmattila]

Hi,

I have recently faced very strange error when trying to update my documents with 1.0.0-beta6 version. The common code for all my trials is as follows:

$dm = $this->get('doctrine_mongodb.odm.default_document_manager');
$session = $dm->getRepository('BrowserSession')->find($this->get('session')->getId());
$session->incrementRequests();

// Continues with one of the code snippets below

1. If I try to call $dm->persist($session); $dm->flush(); an exception "Undefined index: requests in Doctrine/ODM/MongoDB/UnitOfWork.php line 736" is thrown.

2. $dm->flush($session); works properly.

3. $dm->flush(); does not do anything.

I am slightly confused what's going on. Previously, code snippet 1 has worked properly.

The document:

/**
 * @MongoDB\Document()
 * @MongoDB\ChangeTrackingPolicy("DEFERRED_EXPLICIT") 
 */
class BrowserSession
{

    // ID and other fields are here

    /**
     * @MongoDB\Increment
     * @var integer
     */
    protected $requests = 0;

    public function incrementRequests() { $this->requests++; }
}

This may be related to #483 (assuming the field name, and not type, is the problem in that issue).

As expected this is working correctly in latest ODM, here's passing test case :)

<?php

namespace Doctrine\ODM\MongoDB\Tests\Functional\Ticket;

use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;

class GH433Test extends \Doctrine\ODM\MongoDB\Tests\BaseTest
{
    public function testTest()
    {
        $session = new BrowserSession();
        $this->dm->persist($session);
        $this->dm->flush();
        $this->dm->clear();

        $session = $this->dm->getRepository(get_class($session))->find($session->id);
        $session->incrementRequests();
        $this->dm->persist($session);
        $this->dm->flush();
        $this->dm->clear();

        $session = $this->dm->getRepository(get_class($session))->find($session->id);
        $this->assertEquals(1, $session->requests);
    }
}

/**
 * @MongoDB\Document()
 * @MongoDB\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
 */
class BrowserSession
{
    /** @MongoDB\Id */
    public $id;

    /**
     * @MongoDB\Increment
     * @var integer
     */
    public $requests = 0;

    public function incrementRequests() { $this->requests++; }
}
