Я понял это. Надеюсь, этот пост поможет другим, кто разочаровался так же, как и я!
path.php

И для моей логики внешнего интерфейса:
PathController.php
<?php
[...]
/**
* @Extra\Route("/path", name="admin_path")
* @Extra\Route("/path/{id}/edit", name="admin_path_edit", requirements={"id" = "\d+"})
* @Extra\Template()
*/
public function pathAction($id = null)
{
$path = $this->_getObject('Path', $id); // this function either generates a new entity or grabs one from database depending on $id
$form = $this->get('form.factory')->create(new Form\PathType(), $path);
$formHandler = $this->get('form.handler')->create(new Form\PathHandler(), $form);
// process form
if ($formHandler->process()) {
$this->get('session')->setFlash('notice', 'Successfully ' . ($this->_isEdit($path) ? 'edited' : 'added') . ' path!');
return $this->redirect($this->generateUrl('admin_path'));
}
return array(
'path' => $path,
'form' => $form->createView(),
'postUrl' => !$this->_isEdit($path) ? $this->generateUrl('admin_path') : $this->generateUrl('admin_path_edit', array('id' => $path->getId())),
'paths' => $this->_paginate('Path'),
'edit' => $this->_isEdit($path) ? true : false
);
}

PathType.php (форма пути)
<?php
namespace JStout\MainBundle\Form;
use Symfony\Component\Form\AbstractType,
Symfony\Component\Form\FormBuilder;
class PathType extends AbstractType
{
public function buildForm(FormBuilder $builder, array $options)
{
$builder
->add('name')
->add('title')
->add('offers', 'collection', array(
'type' => new PathOfferType(),

'allow_delete' => true

PathOfferType.php (тип коллекции предложений PathType)
<?php
namespace JStout\MainBundle\Form;

PathHandler.php (как я обрабатываю форму)
<?php

Symfony\Component\Form\Form,
Symfony\Component\HttpFoundation\Request,
Doctrine\ORM\EntityManager,

{
protected $form;
protected $request;
protected $entityManager;
public function buildFormHandler(Form $form, Request $request, EntityManager $entityManager)
{
$this->form = $form;
$this->request = $request;
$this->entityManager = $entityManager;
}
public function process()
{
if ('POST' == $this->request->getMethod()) {
// bind form data
$this->form->bindRequest($this->request);
// If form is valid
if ($this->form->isValid() && ($path = $this->form->getData()) instanceOf Path) {
// save offer to the database
$this->entityManager->persist($path);
foreach ($path->getOffers() as $offer) {
$offer->setPath($path);
$this->entityManager->persist($offer);
}
$this->entityManager->flush();
return true;
}
}
return false;
}
}
