Navigating CraueFormFlowBundle when editing existing entity

I created a multipage form using CraueFormFlowBundle. With this form I can create a new entity object or edit an existing one.

I then added the setting

protected $allowDynamicStepNavigation = true;

to allow navigating back and forth through the form's pages, however when using the form to edit an existing object I want to be able to jump straight to any page in the form. This does not seem to work - the object data is loaded and I can press next repeatedly until I get to the desired page.

Is there a way to render the page navigation when editing using CraueFormFlowBundle ?

My template includes:

{% include 'CraueFormFlowBundle:FormFlow:stepList.html.twig' %}

to create the navigation. Here is the editAction:

public function editDriverAction($id) {

$em = $this->getDoctrine()->getManager();

$formData = $em->getRepository('NewgtDriverBundle:NewgtDriver')->find($id);

if (!$formData) {
throw $this->createNotFoundException('Unable to find Driver.');

//$formData = new NewgtDriver(); // Your form data class. Has to be an object, won't work properly with an array.

$flow = $this->get('newgtDriver.form.flow.createDriver'); // must match the flow's service id

// form of the current step
$form = $flow->createForm();
if ($flow->isValid($form)) {

if ($flow->nextStep()) {
// form for the next step
$form = $flow->createForm();
} else {
// flow finished
$em = $this->getDoctrine()->getManager();

$flow->reset(); // remove step data from the session

return $this->redirect($this->generateUrl('driver')); // redirect when done

return $this->render('NewgtDriverBundle:Driver:new.html.twig', array(
'form' => $form->createView(),
'flow' => $flow,

Answer Source

In the source code we see that the flow class must override the method loadStepDescriptions.

My FromFlow Class is like:

namespace MyBundle\Form\Proposal;

use Craue\FormFlowBundle\Form\FormFlow;

class ProposalFlow extends FormFlow {

    protected $maxSteps = 5;

    protected $allowDynamicStepNavigation = true;

    protected function loadStepDescriptions() {
        return array(

Hope this help
