Disabling actions on a radio button

Question

Hello,
I need your help for implementing this behavior on a radio button:
disable any actions on a radio button (no selection is possible) until an event is generated.
It means that this radio buttib still waits for an event for being activated on for another for being desactivated another time?
Any help?

This works fine for me:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.RadioButton;
import javafx.scene.control.ToggleGroup;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class DisabledRadioButtonExample extends Application {
    @Override
    public void start(Stage primaryStage) {
        final RadioButton choice1 = new RadioButton("Choice 1");
        final RadioButton choice2 = new RadioButton("Choice 2");
        final ToggleGroup tg = new ToggleGroup();
        tg.getToggles().addAll(choice1, choice2);
        choice2.setDisable(true);
        final Button enableButton = new Button("Enable");
        enableButton.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent event) {
                choice2.setDisable(false);
                // enable button has no use any more:
                enableButton.setDisable(true);
        final VBox root = new VBox(5);
        root.getChildren().addAll(choice1, choice2, enableButton);
        primaryStage.setScene(new Scene(root, 300, 200));
        primaryStage.show();
    public static void main(String[] args) {
        launch(args);
Can you post a short, complete example which demonstrates the problem?
