Symfony2 Sous-Formulaires

Donc, im essayant d'intégrer un formulaire dans un autre, sans la création d'une classe pour les formes. Voici ce que ive a obtenu

    $form = $this
->buildForm('UserAlert', $alert)
->add('Alert', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Alert', 'property' => 'name', 'required' => true))
->add('Site', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Site', 'property' => 'name', 'required' => false))
->add('Keyword', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Keyword', 'property' => 'name', 'required' => false))
->add('Variant', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Variant', 'property' => 'name', 'required' => false))
->add('Name', 'text');
$uac = $alert->getUserAlertConfig();
$subform = $this
->buildForm('UserAlertConfig', $uac)
->add('EmailAlert', 'choice', array('choices' => array('1' => 'Yes', '0' => 'No'), 'required' => true, 'label' => 'Email Alerts'))
->add('EmailHours', 'text', array('required' => false, 'label' => 'Email Alert Hours'))
->add('TextAlert', 'choice', array('choices' => array('1' => 'Yes', '0' => 'No'), 'required' => true, 'label' => 'Text Alerts'))
->add('TextHours', 'text', array('required' => false, 'label' => 'Text Alert Hours'));
$form->add($subform);
$form = $form->getForm();

cependant, sur le getForm() fonction, de sa en disant

Neither property "form" nor method "getForm()" nor method "isForm()" exists in class "Blah\MgmtBundle\Entity\UserAlert"

quelqu'un a une idée de comment im censé obtenir que cela fonctionne à l'aide de la quickloading trucs?

heres buildForm

public function buildForm($model = '', $data)
{
if (empty($model)) {
throw new \Exception("Must define a model");
}
return $this->get('form.factory')->createBuilder('form', $data, array('data_class' => "\\Blah\\MgmtBundle\\Entity\\$model"));
}

Est-ce contrôleur de code? Ou formulaire personnalisé type de code?
son dans le contrôleur, désolé
Et le buildForm méthode est définie où? Pourriez-vous publier son code source?
ajouté ça à l'op
Pourriez-vous poster quelques infos à propos de l'exception levée? La trace de la pile?
