Symfony 2.3 cascade_validation - validation

Question

i build a form in symfony 2.3. Which shows and save user profile and addresses for this profile.
I have two entities. A user and a address entity. (I will only show some code parts, this code is not complete here)
User Entity:
/**
* #ORM\Entity
* #ORM\Table(name="user")
* #ORM\Entity(repositoryClass="Ebm\UserBundle\Entity\UserRepository")
*/
class User implements AdvancedUserInterface, \Serializable
{
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string", length=255)
*/
protected $firstName;
/**
* #ORM\Column(type="string", length=255)
*/
protected $lastName;
/**
* #ORM\Column(type="string", length=255, unique=true)
*/
private $username;
/**
* #var \Doctrine\Common\Collections\Collection
* #Assert\Valid
* #ORM\ManyToMany(targetEntity="Ebm\UserBundle\Entity\Address", cascade={"persist", "remove"})
* #ORM\JoinTable(name="user_address",
* joinColumns={#ORM\JoinColumn(name="user_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="address_id", referencedColumnName="id")}
* )
*/
protected $addresses;
}
Address Entity:
/**
* #ORM\Entity
* #ORM\Table(name="address")
*/
class Address
{
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string", length=255)
*/
protected $street;
}
And a form which embed the address entity as collection into the user form "usertype".
Usertype:
class UserType extends AbstractType
{
protected $securityContext;
public function __construct(SecurityContext $securityContext)
{
$this->securityContext = $securityContext;
}
/**
* (non-PHPdoc)
* #see \Symfony\Component\Form\AbstractType::buildForm()
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->->add('addresses', 'collection', array(
'type' => new AddressType() ,
'allow_add' => true,
'allow_delete' => true,
'label' => false,
'cascade_validation' => true)
));
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Ebm\UserBundle\Entity\User',
'cascade_validation' => true,
));
}
public function getName()
{
return 'user';
}
}
In my controller the validation part look like this:
$form = $this->createForm($this->get('form.type.user'), $user)->add('save', 'submit');
// On initial page load handleRequest() recognizes that the form was not submitted and does nothing
// isValid returns false
$form->handleRequest($request);
// Check if form isValid
if ($form->isValid()) {
}
And my validation yml (UserBundle/config/validation.yml) file look like this
Ebm\UserBundle\Entity\User:
properties:
firstName:
- NotBlank: ~
- Length:
max: 255
addresses:
- Valid: ~
Ebm\UserBundle\Entity\Address:
properties:
street:
- NotBlank: { message: "validate.not_blank" }
- Type:
type: string
- Length:
max: 255
If the address field is emtyp "street" as example no error was occured. Only validation errors for
entity "user" is displayed.
I'm looking since a week for a solution, i will be very lucky if anyone can help me

As of >= Symfony 2.5 you can use the deep parameter of getErrors
If you want to display errors for compound forms use the deep parameter in the getErrors() function:
// Check if form isValid
if ($form->isValid() === false) {
echo $form->getErrors(true);
}
Otherwise use the all function recursive:
public function getErrorsRecursive($form) {
$errors = array();
foreach ($form->getErrors() as $error) {
$errors[] = $error->getMessage();
}
foreach ($form->all() as $fieldName => $formType) {
if ($errorMessage = $this->getErrorsRecursive($formType)) {
$errors[$fieldName] = array_pop($errorMessage);
}
}
return $errors;
}
