Bugreport cfr. http://groups.google.com/group/doctrine-user/browse_thread/thread/51f5c14377c40e3b

I have a OneToOne relationship defined between a Page and a PageTemplate entity:

class Page
{
    /****
     * @Id
     * @GeneratedValue (strategy="AUTO")
     * @Column (type="integer")
     * 
     * @var int
     */
    protected $id;

    /****
     * @OneToOne(targetEntity="PageTemplate")
     * @JoinColumn(name="templateId", referencedColumnName="templateId")
     *
     * @var PageTemplate
     */
    protected $template;
}

class PageTemplate
{
    /****
     * @Id
     * @GeneratedValue (strategy="AUTO")
     * @Column (type="integer")
     *
     * @var int
     */
    protected $templateId;

    /****
     * @Column (type="string", length="255")
     *
     * @var string
     */
    protected $name;
}

When I try to fetch the Page and it's fully populated associated PageTemplate from the database, I get differect results using different Hydration modes (HYDRATE_OBJECT & HYDRATE_ARRAY):

When using:

$qb = $this->_em->createQueryBuilder();
$q = $qb->select('p', 'tpl')
                ->innerJoin('p.template', 'tpl')
                ->from('Entities\Fratello\Page', 'p')
                ->where($qb->expr()->eq('p.id', $id));

return $q->getQuery()->getSingleResult(); // using HYDRATE_OBJECT

... I get the following:

object(Entities\Fratello\Page)[438]
  protected 'id' => int 1
  protected 'template' => 
    object(Entities\Fratello\PageTemplate)[475]
      protected 'templateId' => null
      protected 'name' => null

On the other hand when I'm using HYDRATE_ARRAY:

$qb = $this->_em->createQueryBuilder();
$q = $qb->select('p', 'tpl')
                ->innerJoin('p.template', 'tpl')
                ->from('Entities\Fratello\Page', 'p')
                ->where($qb->expr()->eq('p.id', $id));

return $q->getQuery()->getSingleResult(\Doctrine\ORM\AbstractQuery::HYDRATE_ARRAY);

.. I get the following:

array
  'id' => int 1
  'template' => &
    array
      'templateId' => int 1
      'name' => string 'template 1' (length=10)

So fetch the object using HYDRATE_ARRAY returns the data I asked for, HYDRATE_OBJECT doesn't (returns a null object)

Tried to reproduce it without success. See the attached testcase. Using latest code from trunk.

Please let us know what needs to be done in that testcase to reproduce your problem. Or provide your own testcase if you have one.

Thanks!

I found the problem in my code. In the Page object constructor I composed an empty PageTemplate instance (null object):

class Page
{
    public function **construct()
    {
        // page template
        $this->template = new PageTemplate();
    }
}

This overrides the PageTemplate object that should be loaded.

Shouldn't the PageTemplate data be loaded after the Page constructor has been executed so it would overrule that one?

Thank you for your time!

You are right, this is not correct. While this could be fixed in isolation I think it is better to fix it implicity by DDC-79 (not calling the constructor on reconstitution of persistent objects).

This should now work without problems due to DDC-79.
