ZF2 + Doctrine2 Annotation Form Required & AllowEmpty

Question

I use Annotation in a Doctrine Entity Class. Annotation for a field are :

   /**
 * @var integer
 *
 * @ORM\Column(name="duree", type="integer", nullable=true)
 *
 * @Form\Type("Zend\Form\Element\Number")
 * @Form\Attributes({"required":false, "placeholder":"Durée", "min":"1", "max":"20"})
 * @Form\Required(false)
 * @Form\AllowEmpty()
 * @Form\Options({"label":"Durée :"})
 * @Form\Filter({"name": "Int"})
 * @Form\Validator({"name":"IsInt"})
 */
private $duree;

So the DB column can be Empty (nullable), and in the form i wan't the same (ie user can leave input empty). I've both annotation Required(false) and allowEmpty, but the form never valid (always got isEmpty for this field).

If i set @Form\Type to "Text", it is working fine (form is valid event if input is empty). But with the class Number, it'is not the same.

I've the same pb with a Select element (correspondinf to a relationship). Annotations are :

    /**
 * @var \Application\Entity\CcCategorie
 *
 * @ORM\ManyToOne(targetEntity="Application\Entity\CcCategorie")
 * @ORM\JoinColumns({
 *   @ORM\JoinColumn(name="categorie", referencedColumnName="id", nullable=true, onDelete="SET NULL")
 * })
 * 
 * @Form\Type("DoctrineModule\Form\Element\ObjectSelect")
 * @Form\Attributes({"type":"select", "required":false})
 * @Form\Options({"label":"Catégorie :"})
 * @Form\Required(false)
 * @Form\AllowEmpty()
 * @Form\Options({
 *      "label":"Catégorie :",
 *      "empty_option": "---",
 *      "target_class": "Application\Entity\CcCategorie",
 *      "property": "label"
 * })     
 */
private $categorie;

But, with this the field has error (isEmpty) if the Select is set to empty option when validating Form.

The only workaround i've found is to set the annotation

 * @Form\Type("\Application\Form\Entity\CcRepriseFieldset")

at the top of the entity class. The class CcRepriseFieldset extend Fieldset, and implement InputFilterProviderInterface. Then i specify the function in this class :

public function getInputFilterSpecification()
    {
        return array(
            array(
                "name" => "duree",
                'required' => false,
                'allow_empty' => true,
            ),
            array(
                "name" => "categorie",
                'required' => false,
                'allow_empty' => true,
            ),
        );
    }

With this it works... But it's not annotations. I don't understand why annotation not work

thanks

Ok i found what is the probleme. Annotation Builder made a array with all fields spec, like this :

 array (size=7)
    'name' => string 'reprise' (length=7)
    'attributes' => array (size=0)
    'elements' => 
      array (size=8)
      1 =>array (size=2)
...
  'fieldsets' => array (size=0) empty
  'type' => string '\Application\Form\Entity\CcRepriseFieldset'
(length=42)
  'input_filter' => 
    array (size=8)
      'name' => 
        array (size=4)
          'name' => string 'name' (length=4)
          'required' => boolean true
          'filters' => 
            array (size=3)
              ...
          'validators' => 
            array (size=2)
...

But this array is the Array for the FieldSet attached to the Entity. So the Zend\Form\Factory never parse this because 'input_filter' are only parse for ZendForm Element not for fieldset (of course because Fieldset doesn't have SetInputFilter method)...

Ok i've a workaround but i'm not very statisfied of it . First i've create a new FormFactory :

namespace Application\Form;
use Zend\Form\FieldsetInterface;
Class EntityFormFactory extends \Zend\Form\Factory {
     public function configureFieldset(FieldsetInterface $fieldset, $spec)
    {
       $fieldset=parent::configureFieldset($fieldset, $spec);

        $fieldset->input_filter_factory= $spec['input_filter'];
        return $fieldset;
    }
}

So this factory add the "input_filter" to a input_filter_factory variable of the fieldset.

Then in the fieldset class is :

class CcRepriseFieldset extends Fieldset implements \Zend\InputFilter\InputFilterProviderInterface
{
   public function getInputFilterSpecification()
    {
        if (isset($this->input_filter_factory)){
            return $this->input_filter_factory;
        }        
    }
}

And finally, when i use annotationbuilder i change the formfactory :

$builder = new AnnotationBuilder($this->_em);
$builder->setFormFactory(new EntityFormFactory());

With this all is working fine... I'm not sur it's the best way to do it.
