Zend Framework 2 FormElementManager factories not working - zend-framework2

Question

Please help me with Zend framework 2:)
I want to create a form with collection of fieldsets using Form Element Manager (absolutely like 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',
),
));
// My fieldset
$this->add(array(
'type' => 'Zend\Form\Element\Collection',
'name' => 'taskbrands',
'options' => array(
'label' => 'Brand of the 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 as 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, my 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 is that form Admin\Form\TaskForm instantiates in factory described in form_elements configuration section, but Admin\Form\TaskbrandFieldset does not. It just invokes.
Trying to understand this problem I found that Admin\Form\TaskForm and Admin\Form\TaskbrandFieldset instantiates with different instances of FormElementManager, first one have my config inside (including factories description), but second has nothing.
Please help me :)

Answer 1

The problem is in your controller. Use
$form = $formManager->get('Admin\Form\TaskForm');
instead of
$form = $formManager->create('Admin\Form\TaskForm');
Remember that you don't have to use $form->init(). It's automatically called, same like in zf1. There is a good tutorial on zf2 site
