zf2 form collection binding

Question

Please, explain me how i can bind values to such a form:

<?php

namespace ZfcAdmin\Form;

use Zend\Form\Form;
use Zend\Form\Element;

class FeelistUploadForm extends Form {
        public function __construct($objectManager) {

                parent::__construct('feelist');

                $this->setAttribute('method', 'post');
                $this->setAttribute('class', 'form');

                $fieldset = new FeelistFieldset($objectManager);
                $fieldset->setUseAsBaseFieldset(true);
                $this->add(array(
                        'type' => 'Zend\Form\Element\Collection',
                        'name' => 'feelist',
                        'options' => array(
                                'label' => 'fee list',
                                'should_create_template' => true,
                                'allow_add' => true,
                                'target_element' => $fieldset,
                        ),
                ));


                $this->add(array(
                        'name' => 'submit',
                        'type' => 'Submit',
                        'attributes' => array(
                                'value' => 'Save',
                                'id' => 'submitbutton',
                                'class' => 'button',
                        ),
                ));

        }
}

and the fieldset

 class FeelistFieldset extends Fieldset implements InputFilterProviderInterface {

        public function __construct($objectManager, $options = array()) {
               $this->setHydrator(new DoctrineHydrator($objectManager, 'InsurancyProduct\Entity\Feelist'))
                        ->setObject(new Feelist());
                parent::__construct('feelist');

                 $this->add(array(
                        'name' => 'id',
                        'type' => 'Hidden',
                 ));


                $this->add(array(
                        'name' => 'csv',
                        'type' => 'Zend\Form\Element\File',
                        'options' => array(
                                'label' => 'csv',
                        ),
                ));


                 $this->add(array(
                        'type' => 'text',
                        'name' => 'valid_from',
                        'options' => array(
                                'label' => 'valid from',
                        ),
                        'attributes'=> array(
                                'id' => 'validfrom',
                        ),
                 ));


        }

     public function getInputFilterSpecification()
     {
         return array(
         );
     }


 }

in the controller i use

$feelist_form = new \ZfcAdmin\Form\FeelistUploadForm($objectManager);
$feelist_form->bind( new feelist());

and i can get values for bind in controller like this

                $feelist = $objectManager
                        ->getRepository('InsurancyProduct\Entity\Feelist')
                        ->findBy(array('product_id' => $id));

i can't bind it to form, it's array of objects, but form recieves only single object. form is of course empty and i dont know how to bind this values to form. Please, dont send me to RFTM, I have been reading it for last 48 hours, about zf2 hydration, forms, etc :(

Probably you can take a look at this example that rlandas wrote and uploaded to github

it is a working project implementing the classic ZendFramework2 Product-Brand-Category sample

this is the code of the controller:

<?php

namespace Product\Controller;

use Product\Table\ProductTable;
use Product\Entity\Product as ProductEntity;
use Product\Form\CreateProduct;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\Http\PhpEnvironment\Response;
use Zend\View\Model\ViewModel;

class ManageController extends AbstractActionController
{

    public function indexAction ()
    {
        $product = $this->getProductTable();
        $products = $product->getAllOrderByName();

        $view = new ViewModel();
        $view->setVariable('products', $products);
        return $view;
    }

    public function viewAction ()
    {
        if ($id = $this->params('id')) {
            $product = $this->getProductTable()
                ->getByProductId($id);
        }

        $view = new ViewModel();
        $view->setVariable('product', $product);
        return $view;
    }

    public function addAction ()
    {
        $form = new CreateProduct();
        $product = $this->getServiceLocator()->get('Product\Entity\Product');
        $form->bind($product);

        $data = array(
            'product' => array(
                'name' => 'product name ' . mt_rand(1, 1000),
                'price' => mt_rand(100.000, 5000.999) / 100,
                'brand' => array(
                    'name' => 'My brand ' . mt_rand(1, 200),
                    'url' => 'http://www.mybrand.com'
