Question

ı在控制台中没有收到任何警告或错误消息。调试模式断点在bean类的valueChangeListener方法中不起作用。另一种方法在bean类的调试模式下工作。 ı还试着听听ajax。（我正在使用maven）有人有想法吗？

beanController.java：

@ManagedBean(name = "beanController")
@ViewScoped
public class BeanController {
public void aSelected(ValueChangeEvent event){

Answer 1

You can use <f:ajax />, like that :   

<f:ajax event="blur" listener="#{beanController.updateDataListener}" update=":#{p:component('tabView')}"/> 


@ManagedBean(name = "beanController")
@SessionScoped
public class BeanController implements Serializable{
   private String a;
   public void updateDataListener(AjaxBehaviorEvent event)
    {
          ......
    }
}

调试模式断点在valueChangeListener中不起作用
