title: Symfony2 dynamic select box - validation fails
body: <p>I'm making an application where users can add their pets (cats and dogs). 
  The app has an "pet input form", where cat/dog breeds are translated into multiple languages, depending on the user. The breeds are added dynamically (using AJAX), based on the pet type selection - so if user selects "dog", the "breed" selection box is populated with dog breeds, and vice versa.
  The problem is, that after submit I get an error:</p>
  
  <blockquote>
    <p>Unable to reverse value for property path "breed": The choice "[Translated breed value]" does not exist or is not unique</p>
  </blockquote>
  
  <p>Is there either a way to disable validation for the select box, or either make it so that it "accepts" translated values as well?</p>
  
  <p>Thanks!</p>
