Child types are not checked using isValid () in symfony2

Question

Child types are not checked using isValid () in symfony2

I have a problem regarding the validation of form children. I have a type that contains several types of another type. This subtype requires one field, one of which is not required. But both of them are empty, the form is verified. Here are my classes

class PassengerList { /** * @Assert\Valid() //If it an array of objet, should validate all the object of the list *traverse */ protected $passengers; /** * @Assert\Valid */ protected $passengers_child; /** * @Assert\Valid */ protected $passengers_baby; }

passengerListType

 class PassengerListType extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { $builder->add('passengers','collection', array( 'type' => new PassengerType(), 'allow_add' => false, 'required'=> true, 'allow_delete' => false)); $builder->add('passengers_child','collection', array( 'type' => new PassengerChildType(), 'allow_add' => true, 'allow_delete' => false)); $builder->add('passengers_baby','collection', array( 'type' => new PassengerBabyType(), 'allow_add' => true, 'allow_delete' => false)); } function getName() { return 'passenger_list'; } }

PassengerType

 class PassengerType extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { $date_params = array("widget"=>"single_text","input"=>"datetime",'format' => 'dd-MM-yyyy',); $builder ->add('civility', 'choice', array("choices"=>Passenger::getCivilityList())) ->add('birthdate','date',$date_params) ->add('last_name','text',array('required'=>true)) ->add('first_name','text',array('required'=>false)) ->add('type','hidden'); } function getName() { return 'passenger'; } public function getDefaultOptions(array $options) { return array( 'data_class' => 'Travelyo\CoreBundle\Entity\Passenger', ); } }
