- *  <p>SplitViewNavigator lets you  display the first navigator in a Callout component.  
- *  When you call the <code>showFirstViewNavigatorInCallout()</code> method, the
- *  first navigator is displayed in a callout until the
- *  <code>hideViewNavigatorCallout()</code> method is called, or the user
- *  touches outside the bounds of the callout.  
- *  It is important to note that when a navigator is displayed in a callout, 
+ *  <p>SplitViewNavigator lets you  display the first navigator in a 
+ *  popup.  By default, it uses a Callout component.  
+ *  When you call the <code>showFirstViewNavigatorInPopUp()</code> method, the
+ *  first navigator is displayed in a popup until the
+ *  <code>hideViewNavigatorPopUp()</code> method is called, or the user
+ *  touches outside the bounds of the popup.  
+ *  It is important to note that when a navigator is displayed in a popup, 
  *  it is reparented as a child of that container.  
  *  This means that using IVisualElementContainer methods such as
  *  <code>getElementAt()</code> on SplitViewNavigator may not return the 

    {
        var navigator:ViewNavigatorBase = event.target as ViewNavigatorBase;
    
        if (event.type == FlexEvent.HIDE && navigator == _calloutNavigator)
            hideViewNavigatorCallout();

        navigator.includeInLayout = navigator.visible;
    }

 *  If you want to access the first or second  navigator, Adobe recommends 
 *  that you use the <code>getViewNavigatorAt()</code>  method.  
 *  This method always returns the correct navigator regardless of whether 
 *  a navigator is in a popup or not.</p>
