[flexcoders] remove ToolTip

[Pablo]

Hi All.

package components
{
   import mx.core.IToolTip;
   import mx.managers.ToolTipManager;

   public class FastSearchPanel
   {
       private var parent:AdvancedTitleWindow;
       private var tooltip:IToolTip;

       public function FastSearchPanel(__parent:AdvancedTitleWindow)
       {
           parent=__parent;
       }

       public function showString(__string:String):void
       {
           if (tooltip==null)
           {
               open();
           }
           tooltip.text=__string
       }

       public function open():void
       {
           tooltip=ToolTipManager.createToolTip("",parent.x,parent.y);
       }

       public function close():void
       {
           if (tooltip!=null)
           {
               ToolTipManager.destroyToolTip(tooltip)
           }
       }
   }
}

when calling ToolTipManager.destroyToolTip(tooltip) builder display error:

ArgumentError: Error #2025: The supplied DisplayObject must be a child of
