title: iPad safari modalpopup issue
body: <p>I am developing a web application which is compatible with iPad.</p>
  
  <p>Earlier I was testing on iOS version 3.2, and all modal dialog popups are returning values just fine to the parent window. But after upgrading my iOS to 4.3, it is behaving odd. Now, on iPad, it is returning a value, but is not updating the field until I click on another field or the same field (HTML text field).</p>
  
  <p>I am opening modal popup using window.open();</p>
  
  <p>And returning using window.opener.oaEventiPad(retValArray);
  oaEventiPad is function which is responsible for setting updated value.</p>
  
  <p>Can anyone please help ??</p>
  
  <p>Thanks,</p>
