I'm not sure what library uses ButtonListenerAdapters, maybe GWT-EXT? But vanilla GWT works:
/** * This is the entry point method. */ final VerticalPanel m_content = new VerticalPanel(); Button button1 = new Button("Click Me"); Button button2 = new Button("Ta-daaa!"); public void onModuleLoad() { //Ring Menu Test. RootPanel.get().add(m_content); m_content.add(button1); button1.addClickListener(new ClickListener() { public void onClick(Widget sender) { m_content.add(button2); } }); } Try mimicking that but with your UI library, see if it works.
