title: <ui:debug/> tag not working in Facelets (JSF 2.0)
body: <p>I am doing a project using JSF 2.0 and Facelets.</p>
  
  <p>I have read documentations that the <code>&lt;ui:debug/&gt;</code> tag gives valuable troubleshooting information upon pressing CTRL-SHIFT-D. But this never works for me. Please anyone tell me what am I missing.</p>
  
  <p>(I tried with various hotkeys, still no success. eg: <code>&lt;ui:debug hotkey="a"/&gt;</code>)</p>
