Symfony 2 - 从表单集合中的oneToMany关系中删除项目

I'm trying to delete an item in my form but nothing happens (not even an error... but I can edit without problem !)

I have a Collection of Forms Embedded with 3 levels (it's about legal notices of my website divided into sub level)

Here are my Entities :

First Level named "MentionLegaleNv1" in OneToMany 

class MentionLegaleNv1 {

    /**
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\Column(name="titre", type="string", length=50, nullable=false)
     */
    private $titre;

    /**
     * @ORM\OneToMany(targetEntity="MentionLegaleNv2", mappedBy="MentionsLegalesNv1", cascade={"persist", "remove"})
     */
    private $MentionsLegalesNv2;

    /**
     * Constructor
     */
    public function __construct() {
        $this->MentionsLegalesNv2 = new \Doctrine\Common\Collections\ArrayCollection();
    }

    /**
     * Get id
     *
     * @return integer 
     */
    public function getId() {
        return $this->id;
    }

    /**
     * Set titre
     *
     * @param string $titre
     * @return MentionLegaleNv1
     */
    public function setTitre($titre) {
        $this->titre = $titre;

        return $this;
    }

    /**
     * Get titre
     *
     * @return string 
     */
    public function getTitre() {
        return $this->titre;
    }

    /**
     * Add MentionsLegalesNv2
     *
     * @param \Video2Learn\BddBundle\Entity\MentionLegaleNv2 $mentionsLegalesNv2
     * @return MentionLegaleNv1
     */
    public function addMentionsLegalesNv2(\Video2Learn\BddBundle\Entity\MentionLegaleNv2 $mentionsLegalesNv2) {
        $mentionsLegalesNv2->setMentionLegaleNv1($this);
        $this->MentionsLegalesNv2[] = $mentionsLegalesNv2;

        return $this;
    }

    /**
     * Remove MentionsLegalesNv2
     *
     * @param \Video2Learn\BddBundle\Entity\MentionLegaleNv2 $mentionsLegalesNv2
     */
    public function removeMentionsLegalesNv2(\Video2Learn\BddBundle\Entity\MentionLegaleNv2 $mentionsLegalesNv2) {
        $this->MentionsLegalesNv2->removeElement($mentionsLegalesNv2);
    }

    /**
     * Get MentionsLegalesNv2
     *
     * @return \Doctrine\Common\Collections\Collection 
     */
    public function getMentionsLegalesNv2() {
        return $this->MentionsLegalesNv2;
    }

The second named "MentionLegaleNv2" in ManyToOne and OneToMany

class MentionLegaleNv2 {

    /**
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\Id

     */
    private $id;

    /**
     * @ORM\Column(name="titre", type="string", length=50, nullable=false)
     */
    private $titre;

    /**
     * @ORM\OneToMany(targetEntity="MentionLegaleNv3", mappedBy="MentionsLegalesNv2", cascade={"persist", "remove"})
     */
    private $MentionsLegalesNv3;

    /**
     * @ORM\ManyToOne(targetEntity="MentionLegaleNv1", inversedBy="MentionsLegalesNv2")
     */
    private $MentionsLegalesNv1;

    /**
     * Constructor
     */
    public function __construct() {
        $this->MentionsLegalesNv3 = new \Doctrine\Common\Collections\ArrayCollection();

    /**
     * Get id

    public function getId() {

    }

    /**

        return $this;
    }

    /**
     * Get titre
     *
     * @return string 
     */
    public function getTitre() {
        return $this->titre;
    }

    /**
     * Add MentionsLegalesNv3
     *
     * @param \Video2Learn\BddBundle\Entity\MentionLegaleNv3 $mentionsLegalesNv3
     * @return MentionLegaleNv2
     */
    public function addMentionsLegalesNv3(\Video2Learn\BddBundle\Entity\MentionLegaleNv3 $mentionsLegalesNv3) {
        $mentionsLegalesNv3->setMentionLegaleNv2($this);
        $this->MentionsLegalesNv3[] = $mentionsLegalesNv3;

        return $this;
    }

    /**
     * Remove MentionsLegalesNv3
     *
     * @param \Video2Learn\BddBundle\Entity\MentionLegaleNv3 $mentionsLegalesNv3
     */
    public function removeMentionsLegalesNv3(\Video2Learn\BddBundle\Entity\MentionLegaleNv3 $mentionsLegalesNv3) {
        $this->MentionsLegalesNv3->removeElement($mentionsLegalesNv3);
    }

    /**
     * Get MentionsLegalesNv3
     *
     * @return \Doctrine\Common\Collections\Collection 
     */
    public function getMentionsLegalesNv3() {
        return $this->MentionsLegalesNv3;
    }

    /**
     * Set MentionsLegalesNv1
     *
     * @param \Video2Learn\BddBundle\Entity\MentionLegaleNv1 $mentionsLegalesNv1
     * @return MentionLegaleNv2
     */
    public function setMentionsLegalesNv1(\Video2Learn\BddBundle\Entity\MentionLegaleNv1 $mentionsLegalesNv1 = null) {

        return $this;
    }

    /**
     * Get MentionsLegalesNv1

     */
    public function getMentionsLegalesNv1() {
        return $this->MentionsLegalesNv1;
    }

The last Level named "MentionLegaleNv3" in ManyToOne

class MentionLegaleNv3 {

    /**

    public function getName() {
        return 'video2learn_administrationbundle_mentionlegalenv3';
    }

}

And my controller :

class MentionsLegalesController extends Controller {

    public function mentionLegalesAction(Request $request) {

        $em = $this->getDoctrine()->getManager();

        $ML = $em->getRepository('Video2LearnBddBundle:MentionLegaleNv0')->findOneById(1);

        if ($request->getMethod() == 'GET') {

                $form = $this->createForm(new MentionLegaleNv0Type(), $ML);
        }

        if ($request->isMethod('POST')) {
            $form = $this->createForm(new MentionLegaleNv0Type(), $ML);
            $form->handleRequest($request);

            if ($form->isValid()) {
                $ML = $form->getData();
                $em->persist($ML);
                $em->flush();
                return $this->redirect($this->generateUrl('administration_mentions_legales'));
            }
        }

        return $this->render('Video2LearnAdministrationBundle:Pages:mentions_legales.html.twig', array(
                    'form' => $form->createView(),

        ));
    }

}

I found that in CookBook of Symfony (http://symfony.com/doc/current/cookbook/form/form_collections.html) and I tried that but without success...

class MentionsLegalesController extends Controller {

    public function mentionLegalesAction(Request $request) {

        $em = $this->getDoctrine()->getManager();

        $ML = $em->getRepository('Video2LearnBddBundle:MentionLegaleNv1')->findOneById(1);

        foreach ($ML->getMentionsLegalesNv2() as $tag) {
            $originalTags->add($tag);
        }
        if ($request->getMethod() == 'GET') {
            $form = $this->createForm(new MentionLegaleNv1Type(), $ML);
        }

        if ($request->isMethod('POST')) {
            $form = $this->createForm(new MentionLegaleNv1Type(), $ML);
            $form->handleRequest($request);

            if ($form->isValid()) {
                foreach ($originalTags as $tag) {
                    if ($ML->getMentionsLegalesNv2()->contains($tag) == false) {
                        $em->persist($tag);
                    }
                }

                $em->persist($ML);
                $em->flush();

                return $this->redirect($this->generateUrl('administration_mentions_legales'));
            }
        }

        return $this->render('Video2LearnAdministrationBundle:Pages:mentions_legales.html.twig', array(
                    'form' => $form->createView(),
        ));
    }

}

How can I do to delete item in MentionLegaleNv2 or MentionLegaleNv3 ??

Thanks for your help !

    I did by an other way ...

    I did that :

    if ($form->isValid()) {

            // supprime la relation entre le tag et la « Task »
            foreach ($originalMentionsLegalesNv1 as $mlnv2) {
                if ($MentionsLegalesNv1->getMentionsLegalesNv2()->contains($mlnv2) == false) {

                    $em->remove($mlnv2);
                }
            }

            $em->persist($MentionsLegalesNv1);
            $em->flush();
