Entity not found on Symfony 2 form - php

Question

I generated with the smyfony2 cli tool a CRUD for a entity. Now i want to use the edit function from the CRUD.
First, the code
/**
* Displays a form to edit an existing Poi entity.
*
* #Route("/poi/{id}/edit", name="poi_edit", requirements={"id" = "\d+"})
* #Method("GET")
* #Template()
*/
public function editAction($id){
$em = $this->getDoctrine()->getManager('default')->getRepository('Project\Bundle\ProjectBundle\Entity\Poi');
$entity = $em->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find Poi entity.');
}
$editForm = $this->createEditForm($entity);
return array(
'entity' => $entity,
'edit_form' => $editForm->createView()
);
}
/**
* Creates a form to edit a Poi entity.
*
* #param Poi $entity The entity
*
* #return \Symfony\Component\Form\Form The form
*/
private function createEditForm(Poi $entity)
{
$form = $this->createForm(new PoiType(), $entity, array(
'action' => $this->generateUrl('poi_update', array('id' => $entity->getId())),
'method' => 'PUT',
));
$form->add('submit', 'submit', array('label' => 'Update'));
return $form;
}
But i receive a "Entity not found" error. Of course i first of all i thought about the throw of the NotFoundException, so i commented it out, but still i get the error.
Then i debugged the code and the entity will be found. It's also existing in the database.
I debugged further and found out that the error is thrown somewhere in the Symfony2 Form stack which generates the form, which is called in the createEditForm action.
Do i clearly miss something? What is my error?
My Symfony2 dev log also just says that a NotFoundException was thrown, no further information there to be found.
I have another entity with a generated CRUD, but there i build the form in the createEditForm by myself because of certain fields that shouldn't be displayed. Do i need to create the form by myself or am i doing something obviously wrong?
Also the PoiType code
class PoiType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
->add('date')
->add('situation')
->add('description')
->add('isPrivate')
->add('image')
->add('audio')
->add('country')
->add('category')
;
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Project\Bundle\ProjectBundle\Entity\Poi'
));
}
/**
* #return string
*/
public function getName()
{
return 'project_bundle_projectbundle_poi';
}
}
This is the Error i get:
CRITICAL - Uncaught PHP Exception Doctrine\ORM\EntityNotFoundException: "Entity was not found." at /var/www/project-symfony/vendor/doctrine/orm/lib/Doctrine/ORM/Proxy/ProxyFactory.php line 177

Try adding a backslash prefix to your data_class in your FormType as such:
'data_class' => '\Project\Bundle\ProjectBundle\Entity\Poi',
