The class 'Symfony\Component\Form\Form' was not found in the chain configured namespaces during Form Submission

Question

I'm building an interface that will allow people in the office to edit details of specific records. Currently I have a form like this:

view.html.twig

<!-- Modal Windows: Edit Instructor Personal Details -->
<div id="editPersonal" style="display:none;">
    <div class="modal-head">
        <h2>Edit Personal Details For: <font-color="red !important">{{instructor.firstName}} {{instructor.surname}}</font></h2>
    </div>
    <div class="modal-body">
        <form action="#" method="post" {{ form_enctype(ipde) }} id="editPersonalDetails" class="modaledit">
        <table class="modalform-col1">
            <tbody>
                <tr class="hidden">
                    <th>{{ form_label(ipde.id, 'ID*', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.id) }}
                        {{ form_widget(ipde.id, { 'attr': {'class': 'textfield'}}) }}
                    </td>
                </tr>
                <tr>
                    <th>{{ form_label(ipde.firstName, 'First Name*', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.firstName) }}
                        {{ form_widget(ipde.firstName, { 'attr': {'class': 'text'}}) }}
                    </td>
                </tr>
                <tr>
                    <th>{{ form_label(ipde.surname, 'Surname*', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.surname) }}
                        {{ form_widget(ipde.surname, { 'attr': {'class': 'text'}}) }}
                    </td>
                </tr>
                <tr>
                    <th>{{ form_label(ipde.address1, 'Address Line 1*', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.address1) }}
                        {{ form_widget(ipde.address1, { 'attr': {'class': 'text'}}) }}
                    </td>
                </tr>
                <tr>
                    <th>{{ form_label(ipde.address2, 'Address Line 2', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.address2) }}
                        {{ form_widget(ipde.address2, { 'attr': {'class': 'text'}}) }}
                    </td>
                </tr>
                <tr>
                    <th>{{ form_label(ipde.town, 'Town*', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.town) }}
                        {{ form_widget(ipde.town, { 'attr': {'class': 'text'}}) }}
                    </td>
                </tr>
                <tr>
                    <th>{{ form_label(ipde.county, 'County*', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.county) }}
                        {{ form_widget(ipde.county, { 'attr': {'class': 'text'}}) }}
                    </td>
                </tr>
                <tr>
                    <th>{{ form_label(ipde.postcode, 'Postcode*', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.postcode) }}
                        {{ form_widget(ipde.postcode, { 'attr': {'class': 'text'}}) }}
                    </td>
                </tr>
                <tr>
                    <th>{{ form_label(ipde.email, 'Email*', { 'attr': {'class': 'title'} }) }}</th>
                    <td>
                        {{ form_errors(ipde.email) }}
                        {{ form_widget(ipde.email, { 'attr': {'class': 'text'}}) }}
                    </td>
                </tr>
            </tbody>
        </table>
    </div>
    <div class="modal-footer">
        <div class="modal-placeright">
            <a href="#close" rel="modal:close" class="closebutton">Close Without Saving</a>
            <input type="submit" value="Save Changes" id="savebuttonpr" class="savebutton" />
            {{ form_rest(ipde) }} 
        </div>
    </div>
</div>

And my Controller looks like this:

DefaultController.php

<?php

namespace PCUK\InstructorBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use PCUK\InstructorBundle\Form\IpdeType;
use PCUK\InstructorBundle\Form\IrType;
use PCUK\InstructorBundle\Form\BaType;
use Symfony\Component\HttpFoundation\Request;

class DefaultController extends Controller
{

    public function viewAction($instructor, Request $request)
    {
        // Database connection
        $insrep = $this->getDoctrine()->getManager();

        // Get Instructor from Entity for Form use
        $instructorQ = $insrep->getRepository('InstructorBundle:MapInstructors')->find($instructor);

        // Get Shared Branches from Entity for Form use
        $instructorS = $insrep->getRepository('InstructorBundle:MapInstructorShared')->find($instructor);

        // Generate Form to edit Instructor Personal Details
        $ipde = $this->createForm( new IpdeType(), $instructorQ);

        // Handle Form submission to edit Instructor Personal Details
        if ($request->getMethod() == 'POST') {
            $ipde->bind($request);

            if ($ipde->isValid()) {
                // perform some action, such as saving the task to the database

                //if ($this->request->isXmlHttpRequest()){
                       //return data ajax requires.
                //}
                $em = $this->getDoctrine()->getManager();
                $em->persist($ipde);
                $em->flush();


                return $this->redirect($this->generateUrl('task_success'));
            }
        }

        // Generate Form to edit Instructor Records
        $ir = $this->createForm( new IrType(), $instructorQ);

        // Generate Form to edit Instructor Records
        $ba = $this->createForm( new BaType(), $instructorS);

        // Return data to view
        return $this->render('InstructorBundle:Default:view.html.twig', array(
            'ipde' => $ipde->createView(),
            'ir' => $ir->createView(),
            'ba' => $ba->createView()
        ));
    }
}

However, when I go to submit the form I get the following error:

"The class 'Symfony\Component\Form\Form' was not found in the chain configured namespaces PCUK\InstructorBundle\Entity"

I have built a Symfony2 project before and I've referenced it against this current project to see if I've included the Symfony\Component\Form\Form, if that's actually what the problem is.

What's happening?

Answer 1

You are persisting $ipde which happens to be a form, not an entity !

That's probably the source of error.

Answer 2

Do you have a "use" statement in all of your *Type() classes? i guess it should be like

use Symfony\Component\Form\AbstractType;

AbstractType have a use of Form namespace.
