Symfony2.3: Validation errors not rendered

Question

A contact form specifies a date, type and distribution center for a set of households. [The set of households is defined as the most recent for that center and is presented via ajax.] The type entity is required and the date must not be in the future. The type constraint is specified in the Contact entity; the date constraint is in a custom validator. If either of these constraints are violated the form is not valid as confirmed in Netbeans debug. Also, the error message appears in Netbeans.. Yet neither of the constraint messages appear in the template. Adding a dump of form_errors to the template provides nothing. I cannot determine why no messages appear.

Contact entity snippet:

namespace Mana\ClientBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use Mana\ClientBundle\Validator\Constraints as ManaAssert;

/**
 * Contact
 *
 * @ORM\Table(name="contact", indexes={@ORM\Index(name="idx_contact_household_idx", columns={"household_id"}), @ORM\Index(name="idx_contact_type_idx", columns={"contact_type_id"}), @ORM\Index(name="idx_contact_center_idx", columns={"center_id"})})
 * @ORM\Entity(repositoryClass="Mana\ClientBundle\Entity\ContactRepository")
 * 
 */
class Contact
{
...
    /**
     * @var \Mana\ClientBundle\Entity\ContactType

     * @ORM\ManyToOne(targetEntity="Mana\ClientBundle\Entity\ContactType", inversedBy="contacts")
     * @ORM\JoinColumn(name="contact_type_id", referencedColumnName="id")
     * @Assert\NotBlank(message="Type must be selected")
     */
    private $contactType;
...
    /**
     * @var \DateTime
     *
     * @ORM\Column(name="contact_date", type="date", nullable=true)

     */
    private $contactDate;

ContactController snippet:

/**
 * @Route("/addContacts", name="contacts_add")
 * @Template("ManaClientBundle:Contact:testLatestContacts.html.twig")
 */
public function addContactsAction(Request $request) {
    $form = $this->createForm(new ContactType());
    $form->handleRequest($request);
    $message = "";
    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();

        $data = $form->getData();
        $contactDate = $data->getContactDate();
        $contactCenter = $data->getCenter();
        $contactType = $data->getContactType();
        $n = count($households);
        foreach ($households as $id) {
            $household = $em->getRepository('ManaClientBundle:Household')->find($id);
            $houseContacts = $household->getContacts();
            $nContacts = count($houseContacts);
            $first = ($nContacts > 0) ? 0 : 1;
            $county = $contactCenter->getCounty();
            $contact = new Contact();
            $contact->setContactDate($contactDate);
            $contact->setCenter($contactCenter);
            $contact->setContactType($contactType);
            $contact->setCounty($county);
            $contact->setFirst($first);
            $household->addContact($contact);
            $em->persist($household);
        }
        $em->flush();
        $center = $contactCenter->getCenter();
        $desc = $contactType->getContactDesc();
        $message = "$n $desc contacts added for $center";
    }
    return array(
        'form' => $form->createView(),
        'title' => 'Add contacts',
        'message' => $message,
    );
}

Template snippet:

<div class="width80">
    <form action="{{ path("contacts_add") }}" method="post">
        <div class="column1">

Answer 1

The error was due to including the code

'error_bubbling' => true,

Since the form was not a child there was no reason for that code to be there. It was an artifact from an earlier version of the application.
