Select2 and many-to-many relations

[abocquet]

Hi,
I've a problem with the select2 entity form type: when I use this type for a many-to-many relation, the link between my entities is not persisted whereas it works with a simple 'entity' form

// it works
$this->form->add('eleves_entity', 'entity', array(
                'class' => 'Kub\UserBundle\Entity\Eleve',
                "multiple" => true,
                "expanded" => true,
                "property_path" => "eleves",
                'query_builder' => function(EleveRepository $er) {

                    return $er->createQueryBuilder('e')
                        ->orderBy('e.username', 'ASC')
                        ->where('e.niveau = :niveau')
                        ->setParameter('niveau', $this->data->getNiveau())
                    ;
                }
            ));

// it doesn't
            $this->form->add('eleves', 'genemu_jqueryselect2_entity', array(
                'class' => 'Kub\UserBundle\Entity\Eleve',
                "multiple" => true,
                "expanded" => true,
                'query_builder' => function(EleveRepository $er) {

                    return $er->createQueryBuilder('e')
                        ->orderBy('e.username', 'ASC')
                        ->where('e.niveau = :niveau')
                        ->setParameter('niveau', $this->data->getNiveau())
                    ;
                }
            ));

I don't think I made a mistake considering that the doc says that we "just have to prefix the type name with genemu_jqueryselect2_* ", so it may be a malfunction of the bundle, that is, by the way, just awesome !

Thank,
Adrien
