title: ExtJS Page redirection
body: <p>This was something which was cracking my head for sometime.</p>
  
  <ol>
  <li>I have a Web Page written in ExtJS+Java EE (Page A). I want to create a
  new browser tab on Button click and show page B.</li>
  <li>B does some operation and does a complete form submit.</li>
  <li>The result of this form submit has to be displayed in A (Which is open all the while).</li>
  </ol>
  
  <p>For Example: </p>
  
  <ol>
  <li>In Page A, I search for the tests available in the my learning management system and display it in a grid.</li>
  <li>When the user clicks on a test, a new window opens with the test's url (Page B).</li>
  <li>Once the user completes the test he clicks the submit in B.</li>
  <li>The results of the test is shown on the grid in Page A.</li>
  </ol>
  
  <p>The big problem is that I done have much control over the Page B or its source.</p>
  
  <p>Any suggestions much appreciated.</p>
