  </code></pre>
  
  <p>I managed to compile the app by enabling V2 compatibility mode like explained here :</p>
  
  <p><a href="http://docs.sencha.com/touch/2-1/#!/guide/command_app-section-3" rel="nofollow">http://docs.sencha.com/touch/2-1/#!/guide/command_app-section-3</a></p>
  
  <p>So what could be the reason why it does not compile without this mode enabled ?</p>
  
  <p>I just went through all my views and double checked the requires statements, they're all there. Also, I don't override any component in my app.</p>
  
  <p><strong>Update</strong></p>
  
  <p>It compiles without errors on one of my coworker's mac.
  I'm on Mountain Lion and this is my <code>java -version</code></p>
  
  <pre><code>java version "1.6.0_37"
  Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
  Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)
