title: Some spark components missing after overlaying flex SDK with AIR
body: <p>I want to create a flex mobile application.</p>
  
  <p>I merged the contents of Adobe AIR SDK 4.0.0(build:1390) with Adobe flex SDK 4.6</p>
  
  <p>Now, when I create a new flex mobile application in Flash Builder, I don't have the "ViewNavigatorApplication" or "View" spark components. Compiling gives the error: </p>
  
  <p><strong>Could not resolve s:ViewNavigatorApplication to a component implementation.</strong> </p>
  
  <p>I noticed that <strong>"mobilecomponents.swc"</strong> disappears from the list of fils after merging AIR SDK with flex SDK. The "ViewNavigatorApplication" component is in this file.</p>
  
  <p>I tried adding the "mobilecomponents.swc" manually, and the result was the application compiled but showd a blank white screen.</p>
  
  <p>The same problem exists with Apache flex SDK 4.12.1</p>
  
  <p>There are no problems when I used this overlayed flex and AIR for a pure AS3 project.</p>
