在方法addTab()中，您可以添加

TabView tabView = new TabView();
Tab newTab = new Tab();            
newTab.setTitle("Tab Title");       
tabView.getChildren().add(newTab); 

并且您应该更新视图以反映新选项卡.使用RequestContext进行Ajax更新.

And you should update the view to reflect the new tab. Use RequestContext for ajax update.

RequestContext context = RequestContext.getCurrentInstance();  
  context.update("tabview");
