Question

I am trying to edit a form i get the form with existing values correctly but when i try to put new data in fields and submit the form i get an error of Call to a member function setName() on a non-object

My controller method is

public function editAction(Request $request){
$request = Request::createFromGlobals();
    $group_id = $request->query->get('id');
    $em = $this->getDoctrine()->getEntityManager();
    $patent_group = $em->getRepository('MunichInnovationGroupBundle:PmPatentgroups')->find($group_id);
    //echo '<pre>';
    //print_r($patent_group);
    //echo '</pre>';
    $form = $this->createForm(new PatentgroupType(), $patent_group);
    if ($request->getMethod() == 'POST') {
        $form->bindRequest($request);
        $name = $form["name"]->getData();
        $description = $form["description"]->getData();
        $patent_group->setName($name);
        $patent_group->setDescription($description);
        $em->flush();
        return $this->redirect($this->generateUrl('MunichInnovationGroupBundle_portfolio'));
    }
    return $this->render('MunichInnovationGroupBundle:Patentgroups:edit.html.twig', array(
            'form' => $form->createView(),
            'group_id' => $group_id
    ));
}

This is what I get in $patent_group

 MunichInnovationGroup\Bundle\Entity\PmPatentgroups Object
(
[id:MunichInnovationGroup\Bundle\Entity\PmPatentgroups:private] => c3e0eb98-ada5-11e1-96a5-9787dec335c2
[name:MunichInnovationGroup\Bundle\Entity\PmPatentgroups:private] => Zoha Ali khan
[description:MunichInnovationGroup\Bundle\Entity\PmPatentgroups:private] => No Description Provided for this Group
[portfolio_id:MunichInnovationGroup\Bundle\Entity\PmPatentgroups:private] => Proxies\MunichInnovationGroupBundleEntityPmPortfoliosProxy Object
    (
        [_entityPersister:Proxies\MunichInnovationGroupBundleEntityPmPortfoliosProxy:private] => Doctrine\ORM\Persisters\BasicEntityPersister Object
            (
                [_class:protected] => Doctrine\ORM\Mapping\ClassMetadata Object
                    (
                        [reflFields] => Array
                            (
                                [id] => ReflectionProperty Object
                                    (
                                        [name] => id
                                        [class] => MunichInnovationGroup\Bundle\Entity\PmPortfolios
                                    )

                                [portfolioName] => ReflectionProperty Object
                                    (
                                        [name] => portfolioName
                                        [class] => MunichInnovationGroup\Bundle\Entity\PmPortfolios
                                    )

What i am doing wrong here as i am getting this error

Call to a member function setName() on a non-object  

Any Ideas?
Thanks in advance

My Fix: Kindly comment whether it is a good solution or not

public function editAction(Request $request){
    $request = Request::createFromGlobals();
    $group_id = $request->query->get('id');
    $em = $this->getDoctrine()->getEntityManager();
    $patentgroup = $em->getRepository('MunichInnovationGroupBundle:PmPatentgroups')->findOneBy(array('id'=>$group_id));
    $form = $this->createForm(new PatentgroupType(), $patentgroup);
    if ($request->getMethod() == 'POST') {
        $form->bindRequest($request);
        $group_id = $form["id"]->getData();
        $name = $form["name"]->getData();
        $description = $form["description"]->getData();
        $em = $this->getDoctrine()->getEntityManager();
        $patentgroup = $em->getRepository('MunichInnovationGroupBundle:PmPatentgroups')->findOneBy(array('id'=>$group_id));
        $patentgroup->setName($name);
        $patentgroup->setDescription($description);
        $em->flush();
        return $this->redirect($this->generateUrl('MunichInnovationGroupBundle_portfolio'));
    }
    return $this->render('MunichInnovationGroupBundle:Patentgroups:edit.html.twig', array(
            'form' => $form->createView(),
            'group_id' => $group_id
    ));
}
