title: AS3 set focus on specific component
body: <p>I have a form with several component: datagrid, textArea, text input...
  For each component FocusIn Event is available.</p>
  <pre><code>var objTarget:String;
       protected function memo_focusInHandler(event:FocusEvent):void
              {
                  objTarget=event.currentTarget.id;       
  }
  </code></pre>
  <p>With memo_focusInHandler, I know which has focus.</p>
  <p>My goal is to backup last focus objet, and re open Windows with focus on this object.
  I try to do this:</p>
  <pre><code>objTarget.setfocus(); 
  </code></pre>
  <p>But it doesn't work. Could you help to found the best way to reach my goal.</p>
