Symfony2.8 project Subform validation by annotation NOT YML No entities or doctrine involvement
Main form validates by annotation OK. Collection field, subform fails to validate. Every field in the subform is passed as valid when the main form fields are valid no matter what you input.
I have tried lots of suggestions online,
'error_bubbling', 'cascade_validation', and the @Valid() tags. Nothing works.
I've added var_dump(...) to RangeValidator class in the symfony2 codebase and it is not created/invoked. To prove its not used, I copied a subform field to the main form and it then calls the framework's validator for range checking which it should do for some fields in the subform, only its not.
Obviously there is more code, including client side javascript but here is a basic code fragment below (hashed up from my code for this question):
Main form:
class SubsetAdd extends AbstractType
{
/**
* @var string
*
* @Assert\NotBlank(
* message="Subset name should not be blank"
* )
* @Assert\Regex(
* pattern="/^[\w\s\d\:\_\-\+]{1,64}$/",
* message="Subset name should contain ..."
* )
*/
protected $subsetName;
/**
* @var string
*
* @Assert\Regex(
* pattern="/^[\d]{1,4}[Kk]{1}$/",
* message="Baud rate should be <n>K"
* )
*/
protected $baud;
/**
* @Assert\Valid()
*/
protected $entries;
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->setMethod('POST');
$builder->add('subsetName',
Type\TextType::class,
array(
'attr' => array(
'title' => 'Subset name string',
),
'required' => true,
'label' => 'Subset'
)
);
$builder->add('baud', Type\ChoiceType::class, array(
'label' => 'Baud',
'attr' => array(
'title' => 'Baud rate',

$builder->add('entries', Type\CollectionType::class, array(

));
if ($options['submit']) {
// manual debugging aid. normally client side ajax does the submit so no button required
$builder->add('submit',Type\SubmitType::class);
}
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setRequired(array(
'submit',

$resolver->setDefaults(array(

);
return $options;
}
public function getName()
{
$cn=substr(__CLASS__,(strlen(__NAMESPACE__)>0?1+strlen(__NAMESPACE__):0)); // class name - namespace
return strtolower(substr($cn,0,1)).substr($cn,1); // lower case first letter
}
public function getBlockPrefix() {

$this->subsetName = $name;
