title: How can I listen for focusIn and focusOut events for a Spark TextArea?
body: <p>I am writing a flex application and I have two Spark TextAreas.  I want to create an EventListener so that when the user clicks on a text area, the text inside the TextArea is cleared:</p>
  
  <pre><code>this.addEventListener(FocusEvent.FOCUS_IN, onFocusIn);
  
  
     private function onFocusIn(ev:FocusEvent):void {
          if (this._showsCaption) {
              this._showsCaption = false;
              super.text = "";
          }
      }
  </code></pre>
  
  <p>Currently I can implement this with a Spark TextInput, but when I click on the TextArea, the focusIn event never fires and the onFocusIn() handler is never called.  </p>
  
  <p>Any thoughts would be much appreciated.</p>
