  I need split view for some pages only and for normal pages I set <code>data-role="page"</code>.
  When i try to load normal pages other than split view pages I am getting the following error</p>
  
  <pre><code>"TypeError: Result of expression 'toPage.data( "page" )' [undefined] is not an object."
  </code></pre>
  
  <p>In <code>jquery.mobile-1.0.js line number 2458</code></p>
  
  <pre><code>toPage.data( "page" )._trigger( "beforeshow", null, { prevPage: fromPage || $( "" ) } );
  </code></pre>
