A piece of code to remove a right/left node from CustomTextField in ControlFX

RemoveNodeFromCustomTextField.java

public static void removeErrorIcon(TextField textField) {
        if (textField instanceof CustomTextField) {
            CustomTextField customTextField = (CustomTextField) textField;
            Platform.runLater(() -> {
               ((StackPane)customTextField.getRight().getParent()).getChildren().remove(customTextField.getRight());
              });
        }
    }
