Zend Framework 2 FormElementManager factories not working -

please me zend framework 2:)

i want create form collection of fieldsets using form element manager (absolutely in official documentation).

my formelementmanager configuration:

'form_elements' => array(     'factories' => array(         'admin\form\taskform' => function($sm) {             $form = new taskform();             $doctrimeentitymanager = $sm->getservicelocator()->get('doctrine\orm\entitymanager');             $form -> setentitymanager($doctrimeentitymanager);             $form -> init();             return $form;         },         'admin\form\taskbrandfieldset' => function($sm) {             $doctrimeentitymanager = $sm->get('doctrine\orm\entitymanager');             $form = new taskbrandfieldset();             $form->setentitymanager($doctrimeentitymanager);             return $form;         },     ) ), 

admin\form\taskform (only problem part):

namespace admin\form; use doctrine\orm\entitymanager; use zend\form\form;  class taskform extends form {  protected $entitymanager;  public function init() {      $this->setattribute('method', 'post');      // id     $this->add(array(         'name' => 'id',         'attributes' => array(             'type' => 'hidden',         ),     ));      // fieldset     $this->add(array(         'type' => 'zend\form\element\collection',         'name' => 'taskbrands',         'options' => array(             'label' => 'brand of product',             'count' => 0,             'should_create_template' => true,             'allow_add' => true,             'target_element' => array(                 'type'=>'admin\form\taskbrandfieldset'                 ),         ),         'attributes' => array(             'id' => 'addressfieldset'         )     )); } } 

admin\form\taskbrandfieldset:

namespace admin\form;  use admin\entity\taskbrand; use zend\form\fieldset; use zend\inputfilter\inputfilterproviderinterface; use zend\stdlib\hydrator\classmethods classmethodshydrator; use zend\servicemanager\servicelocatorawareinterface; use zend\servicemanager\servicelocatorinterface;  class taskbrandfieldset extends fieldset implements inputfilterproviderinterface, servicelocatorawareinterface {  protected $entitymanager; protected $servicelocator;  public function init() {     $this->setname('taskbrandfieldset');     $this->sethydrator(new classmethodshydrator(false))             ->setobject(new taskbrand());      $this->setlabel('taskbrand');      $this->add(array(         'type' => 'doctrinemodule\form\element\objectselect',         'name' => 'brand',         'options' => array(             'object_manager' => $this->getentitymanager(),             'target_class' => 'module\entity\brand',             'property' => 'name',         ),     ));  } } 

and, finally, controller:

 $task = $this->getservicelocator()->get('admin\model\task')->findbypk($id);  $formmanager = $this->getservicelocator()->get('formelementmanager');  $form =  $formmanager->create('admin\form\taskform');  $form->bind($task); 

the problem form admin\form\taskform instantiates in factory described in form_elements configuration section, admin\form\taskbrandfieldset not. invokes.

trying understand problem found admin\form\taskform , admin\form\taskbrandfieldset instantiates different instances of formelementmanager, first 1 have config inside (including factories description), second has nothing.

please me :)

the problem in controller. use

$form = $formmanager->get('admin\form\taskform'); 

instead of

$form = $formmanager->create('admin\form\taskform'); 

remember don't have use $form->init(). it's automatically called, same in zf1. there tutorial on zf2 site
