ZF2-457: Fatal error: Call to undefined method Zend\Form\Element::getCheckedValue() in Zend\Form\View\Helper\FormCheckbox.php on line 48


Got the error shown in Summary when using the formCheckbox helper to render a checkbox. Tested against zendframework-zf2-release-2.0.0rc2-86-g8fb1930

// sample form
namespace Web\Form;
use Zend\Form\Form;
class Test extends Form
    public function __construct($name = null)

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

            'name' => 'testcheck',
            'attributes' => array(
                'type' => 'checkbox',
                'checked' => false,
            'options' => array(
                'label' => 'Test option',

// sample controller
public testAction()
    $form = new \Web\Form\Test();
    return array('form' => $form);

// sample view script
<?php echo $this->formCheckbox($form->get('testcheck')); ?>


The formCheckbox helper requires that the Element is of type Zend\Form\Element\Checkbox in order to get extra information for rendering the checkbox (checked, unchecked, useHiddenElement values).

Added PR to ensure that Checkbox Element is used:

Downgrading issue from Blocker to Major since there is a workaround via Zend\Form\Element\Checkbox.

Patch merged
