How to bind NumberValidator with button.disableProperty()?

[Swapnil722Git]

I want to bind NumberValidator with button.disableProperty();

public class NewController {
   @FXML
    private JFXButton saveButton;

   @FXML
    private JFXTextField numJFXTextField;

    NumberValidator num = new NumberValidator();

    @Override
    public void initialize(URL url, ResourceBundle rb) {
        saveButton.disableProperty().bind(Bindings.isNotEmpty(num.messageProperty())); 

        digitValidator(numJFXTextField, num);
}

    public void digitValidator(JFXTextField jFXTextField, NumberValidator numberValidator) {
        jFXTextField.getValidators().add(numberValidator);
        numberValidator.setMessage("Only numbers are allowed.");
        jFXTextField.setOnKeyTyped((KeyEvent event) -> {
            jFXTextField.validate();
        });
    }
}

I know it wouldn't work since messageProperty is hard-coded and never be empty. So which property I should use to accomplish this?

What about the NumberValidator.hasErrorsProperty() ?
