Hi,
Is there a way to reset a RadioButtonGroup? In other words, programatically unselect the user choice.
I tried clear() and setSelectedItem(null) without success (the UI always shows the selection).
Thx

Hi JC,
trying Vaadin Framework 8.0.6 and the following code:
package com.example.myapplication;
import javax.servlet.annotation.WebServlet;
import com.vaadin.annotations.Theme;
import com.vaadin.annotations.VaadinServletConfiguration;
import com.vaadin.server.VaadinRequest;
import com.vaadin.server.VaadinServlet;
import com.vaadin.ui.Button;
import com.vaadin.ui.RadioButtonGroup;
import com.vaadin.ui.TextField;
import com.vaadin.ui.UI;
import com.vaadin.ui.VerticalLayout;
/**
* This UI is the application entry point. A UI may either represent a browser window
* (or tab) or some part of a html page where a Vaadin application is embedded.
* <p>
* The UI is initialized using {@link #init(VaadinRequest)}. This method is intended to be
* overridden to add component to the user interface and initialize non-component functionality.
*/
@Theme("mytheme")
public class MyUI extends UI {
@Override
protected void init(VaadinRequest vaadinRequest) {
final VerticalLayout layout = new VerticalLayout();
final TextField name = new TextField();
name.setCaption("Type your name here:");
final RadioButtonGroup<String> single = new RadioButtonGroup<>("Single Selection");
single.setItems("Single", "Sola", "Yksi");
Button button = new Button("Click Me");
button.addClickListener(e -> {
System.out.println(single.getSelectedItem());
single.setSelectedItem(null);
System.out.println(single.getSelectedItem());
});
layout.addComponents(name, button, single);
setContent(layout);
}
@WebServlet(urlPatterns = "/*", name = "MyUIServlet", asyncSupported = true)
@VaadinServletConfiguration(ui = MyUI.class, productionMode = false)
public static class MyUIServlet extends VaadinServlet {
}
}
I think you have a valid point.
Select Yksi, press button:
Optional[Yksi]
Optional.empty
Press button:
Optional.empty
Optional.empty
but the graphical representation stays at “Yksi”.
Let’s make this a bug: https://github.com/vaadin/framework/issues/9494
Thank you + Best Regards,

Thx for the follow-up
