ZF2 Nested Collection element has no value - php

Question

I have created a form with nested Collection Customer(Form) -> Categories(Collection/Fieldset) -> Tags(Collection/Fieldset).
It's:
One(Customer) -> Many(Categories)
One(Catogrie) -> Many(Tags)
After bind the customer to the Form it looks like everything is working fine. The Hydrator get the object and the elements where created in Tags.
But in the View the Tag-Elements have no value...
I have checked the Hydrator for typos but everything is fine I copy/paste the index to make sure. When i var_dump the Tags-Collection the objects with value are binded.
I really dont know where the error is, thats why i dont enter some code here I think it would be to much. When you have an idea I can show you the code where you guess the error can be.
Greetings.
Tiega.
EDIT:
Okay I will try to do my best to give you readable code :)
class KontakteController extends AbstractActionController {
public function getKontaktAction()
{
$formManager = $this->serviceLocator->get('FormElementManager');
$kontaktForm = $formManager->get('KontakteManager\Form\KontakteForm');
$id = $this->params()->fromRoute('id');
$kontakt = $this->getKontakte()->getKontakt($id);
if (!$id || !$kontakt) {
return $this->redirect()->toRoute('kontakte', array(
'action' => 'addKontakt'
));
}
$kontakt->initFirmaKommunikation($this->getKommunikation());
$kontakt->initAdressen($this->getAdressen());
$kontakt->initAnsprechpartner($this->getKontakte());
$kontakt->initBankverbindungen($this->getBankverbindung());
$kontakt->initFirmaKategorien($this->getKontakteKategorie());
$kontakt->initPersonKategoiern($this->getKontakteKategorie());
$kontaktForm->bind($kontakt);
return new ViewModel(array(
'kontaktForm' => $kontaktForm,
'geloescht' => $kontakt->geloescht,
'tags' => $this->ladeTags(),
));
}
CustomerFieldset:
class KontakteForm extends Form implements InputFilterProviderInterface {
public function __construct()
{
parent::__construct('kontakt');
$this->setHydrator(new KontaktHydrator())
->setObject(new Kontakt());
$this->add(array(
'type' => 'Zend\Form\Element\Collection',
'name' => 'firmaKategorien',
'options' => array(
'count' => 0,
'allow_add' => true,
'allow_remove' => true,
'should_create_template' => false,
'target_element' => array(
'type' => 'KontakteManager\Form\KontaktKategorieFieldset'
)
)
));
}
/**
* #return array
\*/
public function getInputFilterSpecification()
{
return array();
}
The CategorieFieldset:
class KontaktKategorieFieldset extends Fieldset {
public function __construct()
{
parent::__construct('kontakteKategorie');
$this->setHydrator(new KontaktKategorieFieldsetHydrator())
->setObject(new KontaktKategorie());
$this->add(array(
'name' => 'id',
'type' => 'Zend\Form\Element\Hidden',
'attributes' => array(
'class' => 'form-control',
),
));
$this->add(array(
'name' => 'bezeichnung',
'type' => 'Zend\Form\Element\Text',
'attributes' => array(
'class' => 'form-control',
),
'options' => array(
'label' => 'Kategorie',
),
));
$this->add(array(
'type' => 'Zend\Form\Element\Collection',
'name' => 'tags',
'options' => array(
'count' => 0,
'allow_add' => true,
'allow_remove' => true,
'should_create_template' => false,
'target_element' => array(
'type' => 'KontakteManager\Form\TagFieldset'
)
)
));
}
And the TagFielset:
class TagFieldset extends Fieldset implements InputFilterProviderInterface {
public function __construct()
{
parent::__construct('Tag');
$this->setHydrator(new TagHydrator())
->setObject(new Tag());
$this->add(array(
'name' => 'id',
'type' => 'Zend\Form\Element\Hidden',
'attributes' => array(
'class' => 'form-control',
),
));
$this->add(array(
'name' => 'mehrsprachig',
'type' => 'Zend\Form\Element\Hidden',
'attributes' => array(
'class' => 'form-control',
),
'options' => array(
'label' => 'Mehrsprachig',
),
));
$this->add(array(
'name' => 'kategorieID',
'type' => 'Zend\Form\Element\Hidden',
'attributes' => array(
'class' => 'form-control',
),
));
$this->add(array(
'name' => 'bezeichnung',
'type' => 'Zend\Form\Element\Text',
'attributes' => array(
'class' => 'form-control',
'readonly' => 'readonly',
),
'options' => array(
'label' => 'Bezeichnung',
),
));
}
/**
* #return array
\*/
public function getInputFilterSpecification()
{
return array();
}
And the View code how i try to display the collections
<h5 class="text-primary"><strong>Kategorien</strong></h5>
<hr>
<?php foreach($kontaktForm->get('firmaKategorien') as $element): ?>
<div class="row">
<div class="col-lg-12">
<div class="col-lg-6">
<?php echo $this->formElement($element->get('bezeichnung')); ?>
</div>
<div class="col-lg-6">
<?php foreach($element->get('tags') as $tag): ?>
<?php echo $this->formElement($tag->get('bezeichnung')); ?>
<?php endforeach; ?>
</div>
</div>
</div>
<?php endforeach; ?>
and here an example result:
<h5 class="text-primary"><strong>Kategorien</strong></h5>
<hr>
<div class="row">
<div class="col-lg-12">
<div class="col-lg-6">
<input type="text" name="firmaKategorien[0][bezeichnung]" class="form-control" value="Druckerei">
</div>
<div class="col-lg-6">
<input type="text" name="firmaKategorien[0][tags][0][bezeichnung]" class="form-control" readonly="readonly" value="">
<input type="text" name="firmaKategorien[0][tags][1][bezeichnung]" class="form-control" readonly="readonly" value="">
</div>
</div>

See if this will make any changes
$kontaktForm->bind($kontakt);
//Add this line
$kontaktForm->setData((Array)$kontakt);
