title: Invalid position for property alias
body: <p>I am starting to develop for my shiny new BB10 Dev Alpha B with Cascades (Doubt i can implement a fully-functional Mp3 player on WebWorks, even though i'd really like to) and i've been trying to make QML and C++ play nicely as described in <a href="https://developer.blackberry.com/cascades/documentation/dev/integrating_cpp_qml/index.html" rel="nofollow">https://developer.blackberry.com/cascades/documentation/dev/integrating_cpp_qml/index.html</a> but no matter where i put </p>
  
  <p><code>property alias artistText: artist.Text</code></p>
  
  <p>the QNX Momentics IDE complains about it being on an invalid place. I have not found any guidelines on where said properties ought be so i decided to ask here.</p>
