symfony form collection error bubbling not working as expected - php

Question

I have 2 entities with form types :
User2Type.php is a sub form of Pca2Type.php.
If the form is not filled out properly, the errors from User2Type.php keep bubbling up to the "users" property of Pca2Type.php.
How can I get the errors so they appear next to their appropriate fields instead. I want the username, email, and password errors to appear next to their fields.
I will post the form types.
Pca2Type.php
namespace Homecare\HomecareBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class Pca2Type extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('firstName')
->add('lastName')
->add('umpi')
->add('agency', 'entity', array( 'class' => 'HomecareHomecareBundle:Agency', 'property' => 'agencyName', 'placeholder' => 'N/A' ) )
->add('create','submit', array(
'label' => 'Create Pca'
) )
;
$builder->add('users', 'collection', array('type' => new User4Type(), 'allow_add' => true, 'by_reference' => false, 'error_bubbling' => false ));
}
/**

$resolver->setDefaults(array(

'validation_groups' => array( 'adminCreatePca' ),
