title: Is there a sample of displaying a BBM contact list using Cascades on BB10?
body: <p>I have been struggling for a little while to get the contact list from a BBM connected app so that I can choose a contact to work with.</p>
  
  <p>I am using the bb::platform::bbm::ContactService class, but whenever I call contacts() it comes back as null, even when the registration process is completed.</p>
