Symfony2 Embedded Forms Using the Same Property Path - Error Bubbling Issues

I divided the user account area into different forms, then for the registration form I collect these bits like this:

class RegistrationFormType extends AbstractType
{

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('email', 'email', array(
            'label' => '* Email address:'
        ))
        ->add('account_personal', 'my_personalinfo_form', array(
            'property_path' => 'account'
        ))
        ->add('account_contact', 'my_contactinfo_form', array(
            'property_path' => 'account'
        ))
    ;
}

The problem is that error messages for account_personalbubble up at the top of the form. For example, "Please enter your name" if the first name remains blank in the personal information form. "Personal" and "contact" forms work great in their own forms on their pages.

Error messages for account_contactare accurate and are displayed next to the correct fields.

, ->add ( account_contact), ; account_personal , account_contact !

:

class PersonalInfoType extends AbstractType
{

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('title', 'text')
        ->add('first_name', 'text', array(
            'required' => true,
            'label' => '* First name:'
        ))
        ->add('last_name', 'text', array(
            'required' => true,
            'label' => '* Surname:'
        ))
    ;
}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'My\UserBundle\Entity\Account',
        'validation_groups' => array('personalInfo')
    ));
}

{
    return 'my_personalinfo_form';
}
