Improved Flex Validation: Display Error Tooltip

I combined two validation concepts to arrive at my Improved Flex Validation. The key component is Joel Hooks Form Validation for the Lazy Programmer. I incorporated the UIComponent.callLater() hack for displaying error ToolTips and viola!

Here is what the callLater() looks like:

...
    // display errorTip
    if (showErrorsImmediately && 
        currentControlIsValid == false && 
        supressEvents == false)
    {
        // cast the focussed control to a UIComp to use callLater
        var ffc:UIComponent = focusedFormControl as UIComponent;
        ffc.callLater(showDeferred, [focusedFormControl]);
    }
    
    return currentControlIsValid;
}

private function showDeferred(target:DisplayObject):void {
      target.dispatchEvent(new MouseEvent(MouseEvent.MOUSE_OUT));
      target.dispatchEvent(new MouseEvent(MouseEvent.MOUSE_OVER));
}
