            protected void onError(final AjaxRequestTarget target, Form form) {
               
                log.warn             
                log.debug("onError Calledcalled");

                        // Safe way to view the children components...

                        if (\!formComponent.isValid()){ // If this component failed validation, do something fancy to display it to               
the user...
                            target.addComponent(formComponent);             
                
                            target.appendJavascript("new Effect.Shake($('" + formComponent.getMarkupId() + "'));");
                                    
                       
                    }
                });
            }
