Error when embedding form in Symfony whith collection - forms

Question

I have 2 "simple" entities, and i want to do the classical form embedding
but i have this error : "Neither the property "itemcode" nor one of the methods "getItemcode()", "itemcode()", "isItemcode()", "hasItemcode()", "__get()" exist and have public access in class "NWA\ItemSelectorBundle\Entity\ItemSelector"."
I've seen many posts with this error, but none provided the solution
In the entities i have getItemCode() but why would it be public ?
What is wrong with my construction?
Thank you in advance
Here are my entities (parts relevant to the properties at fault)
class ItemSelector
{
/**
* #var Items[]
*
* #ORM\OneToMany(targetEntity="NWA\ItemSelectorBundle\Entity\Item", mappedBy="itemselector", cascade={"all"})
*/
protected $items;
/**
* Class constructor
*/
public function __construct()
{
$this->items = new ArrayCollection();
}
/**
* Add item
*
* #param \NWA\ItemSelectorBundle\Entity\Item $item
*
* #return ItemSelector
*/
public function addItem(\NWA\ItemSelectorBundle\Entity\Item $item)
{
$this->items[] = $item;
//$item->setItemselector($this);
return $this;
}
/**
* Remove item
*
* #param \NWA\ItemSelectorBundle\Entity\Item $item
*/
public function removeItem(\NWA\ItemSelectorBundle\Entity\Item $item)
{
$this->items->removeElement($item);
}
/**
* Get items
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getItems()
{
return $this->items;
}
}
and
class Item
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="itemcode", type="string", length=255)
*/
protected $itemcode;
/**
* #var ItemSelector
*
* #ORM\ManyToOne(targetEntity="NWA\ItemSelectorBundle\Entity\ItemSelector", inversedBy="items")
* #ORM\JoinColumn(name="itemselector_id", referencedColumnName="id")
*/
protected $itemselector;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set itemcode
*
* #param string $itemcode
*
* #return Item
*/
public function setItemcode($itemcode)
{
$this->itemcode = $itemcode;
return $this;
}
/**
* Get itemcode
*
* #return string
*/
public function getItemcode()
{
return $this->itemcode;
}
/**
* Set itemselector
*
* #param \NWA\ItemSelectorBundle\Entity\ItemSelector $itemselector
*
* #return Item
*/
public function setItemselector(\NWA\ItemSelectorBundle\Entity\ItemSelector $itemselector = null)
{
$this->itemselector = $itemselector;
return $this;
}
/**
* Get itemselector
*
* #return \NWA\ItemSelectorBundle\Entity\ItemSelector
*/
public function getItemselector()
{
return $this->itemselector;
}
}
Then the Form constructors
class ItemSelectorType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add(
'itemcode', 'collection', array(
'type' => new ItemType(),
'prototype' => true,
'allow_add' => true,
'allow_delete' => true
)
);
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'NWA\ItemSelectorBundle\Entity\ItemSelector',
'translation_domain' => 'resource'
));
}
/**
* #return string
*/
public function getName()
{
return 'nwa_itemselector';
}
}
and
class ItemType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add(
'itemcode', 'text', array(
'label' => 'Code'
)
);
;
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'NWA\ItemSelectorBundle\Entity\Item'
));
}
/**
* #return string
*/
public function getName()
{
return 'nwa_itemselectorbundle_item';
}
}
And finally the call in the Controller
public function chooseAction(Request $request, ItemSelector $itemSelector)
{
$form = $this->get('form.factory')
->create(new ItemSelectorType(), $itemSelector);
$form->handleRequest($request);
if ($form->isValid()) {
}
return array(
'_resource' => $itemSelector,
'form' => $form->createView(),
);
}

Maybe you need to rename your field name itemcode to items in ItemSelectorType.
->add(
'items', 'collection', array(
'type' => new ItemType(),
'prototype' => true,
'allow_add' => true,
'allow_delete' => true
)
);
