Symfony2 - Validation not working for embedded Form Type

Question

I have a form that combines two entities (User and Profile).

Validation seems to work on the first part of the form that comes form the User Entity and is the basis

Answer 1

A note to those using Symfony 3.0 and up: the cascade_validation option has been removed. Instead, use the following for embedded forms:

$builder->add('embedded_data', CustomFormType::class, array(
    'constraints' => array(new Valid()),
));

Sorry for adding to this old thread with a slightly off-topic answer (Symfony 3 vs. 2), but finding this information here would have saved me a few hours today.
