title: Focus TextArea after Drag/Drop in ExtJS 4.0.5
body: <p>In my ExtJS Application, the user can drag a row/item from a GridPanel to a TextArea and its content is inserted at the current cursor index of the TextArea.</p>
  
  <p>As soon as I start to drag the GridItem, the TextArea obviously loses focus. 
  When dropping the item, I want to refocus the TextArea (and set the caret/cursor to the old position). I tried calling the focus() method of the TextArea component in the "Drop Event" like so:</p>
  
  <pre><code>notifyDrop: function (ddSource, e, data) {
     //all the insertion stuff which works fine
  
     var textarea = Ext.getCmp("textAreaID");
     textarea.focus(); //doesn't work
  }
  </code></pre>
  
  <p>When I call textarea.focus() from the browser console it works fine, so my guess is that it's the wrong event to call it from. </p>
  
  <p>Thanks in advance!</p>
