Symfony2: my form returns false from isValid() but empty array for getErrors() from unique constraint condition

Question

I have a Customer entity that only has a unique Email field to it. I am trying to edit a customer\'s email and the validation works fine. However I have this in my controller:

Ok, found an answer here:

Symfony2 invalid form without errors

It turns out each form child has it's own separate errors. When doing a var_dump of

$editForm->getChildren()['email']->getErrors()

I get:

array (size=1)
  0 => 
    object(Symfony\Component\Form\FormError)[531]
      private 'message' => string 'A customer under that email address already exists' (length=50)
      protected 'messageTemplate' => string 'A customer under that email address already exists' (length=50)
      protected 'messageParameters' => 
        array (size=0)
          empty
      protected 'messagePluralization' => null

I am still wondering how to determine that the error is because of a unique conflict without parsing the error message string.
