Form not validating correctly zend framework 2

I am trying a custom configuration for a new system wide.

I'm stuck on Form validations using Filter.

Primary Question:

    $form      = new CrudForm($this->getEntityManager());

    $request = $this->getRequest();

    if ($request->isPost()) {

        $filter = new CrudFilter();
        $form->setInputFilter($filter);
        $post = $request->getPost();
        $form->setData($post);
        //$crudLogic->edit($crudLogic->populateEntity($post)->update());

        if ($form->isValid()) {
        }
     }

This Form Never Get Validated. But what makes me crazy is that this is the Form is simple:

namespace Manager\Form;
use Zend\Form\Form;
use Zend\Form\Element;
use Doctrine\ORM\EntityManager;
class CrudForm extends Form
{
    public function __construct(EntityManager $em)
    {
        parent::__construct('Crud');
        $this->setAttribute('method', 'post');

        $idcrud = new Element('idCrud');
        $idcrud->setAttributes(array(
            'name' => 'idCrud',
            'id' => 'idCrud',
            'type' => 'text',
        ));
        $idcrud->setLabel('Id Crud');

        $this->add($idcrud);

        $idmodule = array(
            'name' => 'idModule',
            'type' => 'DoctrineModule\Form\Element\ObjectSelect',
            'options' => array(
                'label' =>'Id Module',
                'object_manager' => $em,
                'target_class' => 'Manager\Entity\Module',
                'property' => 'name',
                'empty_option' => 'Choose',
            ),
        );
        $this->add($idmodule);

        $name = new Element('name');
        $name->setAttributes(array(
            'name' => 'name',
            'id' => 'name',
            'type' => 'text',
        ));
        $name->setLabel('Name');

        $this->add($name);

        $createddate = new Element\Date('createdDate');
        $createddate->setAttributes(array(
            'name' => 'createdDate',
            'id' => 'createdDate',
            'type' => 'date',
            'size' => '30',
            'class' => 'datepicker',
        ));
        $createddate->setLabel('Created Date');

        $this->add($createddate);

        $updateddate = new Element\Date('updatedDate');
        $updateddate->setAttributes(array(
            'name' => 'updatedDate',
            'id' => 'updatedDate',
            'type' => 'date',
            'size' => '30',
            'class' => 'datepicker',
        ));
        $updateddate->setLabel('Updated Date');

        $this->add($updateddate);

        $send = new Element('submit');
        $send->setValue('Submit');
        $send->setAttributes(array(
            'type'  => 'submit'
        ));
        $this->add($send);
    }
}

And The Filter:

namespace Manager\Filter;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;

class CrudFilter extends InputFilter
{
    public function __construct()
    {

        $this->add(array(
            'name' => 'IdCrud'
            ,'filters'  => array(
                array('name' => 'Int'),
            )
        ));
        $this->add(array(
            'name' => 'IdModule'
            ,'required' => true
            ,'filters'  => array(
                array('name' => 'Int'),
            )
        ));
        $this->add(array(
            'name' => 'Name'
            ,'required' => true
            ,'filters'  => array(
                array('name' => 'StripTags'),
                array('name' => 'StringTrim'),
            ),
            'validators' => array(
                array(
                    'name'    => 'StringLength',
                    'options' => array(
                    'encoding' => 'UTF-8',
                    'min'      => 1,
                    'max'      =>150,
                ),
            ),
        )
    ));

}

}

To me surprise at all, the erros after i do $form->isValid() is returning like it:

array (size=2)
  'createdDate' => 
    array (size=1)
      'isEmpty' => string 'Value is required and can't be empty' (length=36)
  'updatedDate' => 
    array (size=1)
      'isEmpty' => string 'Value is required and can't be empty' (length=36)

So it is the problem, i not even declare validation on those fields, just for idModule and name inputs, i'm losting time on one think that i not even declare!

Where can is coming those validation?

Edit: By the way i not even echoing the createdDate and updatedDate on view, is just for database control, i not need those fields to be validated on Form scope.

Edit2: By removing the createDate and updateDate from Form, i get zero message erros, but even not validating the form! I need the form to be valid.

First - Do make sure that the database table structure does not have those fields (createdDate and updatedDate) as NOT NULL.

Second - InputFilter has more like - strict behavior. If you want any element to be required or not, then you have to specify that explicitly.

Try setting the Filter for 'createdDate' and 'updatedDate' as 'required' => false,

$this->add(array(
    'name' => 'createdDate',
    'required' => false,
    ....
));

$this->add(array(
    'name' => 'updatedDate',
    'required' => false,
    ....
));

At least this way, those messages wont be added in the errors() array.
