  <p>So it looks like it is not loading a proper render engine for my map. I tried updating my SDK and updated the OS on the phone using the blackberry OS update to no avail. </p>
  
  <p>Here is the full Qml for my map:</p>
  
  <pre><code>import bb.cascades 1.0
  import bb.cascades.maps 1.0
  
  Page {
      Container {
          layout: StackLayout {
          }
          MapView {
              id: mapview
              latitude: 43.468245
              longitude: -80.519603
              altitude: 10000
          }
      }
  }
  </code></pre>
  
  <p>More details:
  OS Version: 10.9.10.35
  Native SDK: 10.0.9.1673
  Momentics Version: 10.0.9</p>
  
  <p>I tried another SDK version too, 10.0.10.xxx and it didn't work either.</p>
