Question

我使用p：messages的autoUpdate属性，但它不起作用，网页上不会显示消息。有趣的是，如果valdation失败，则显示消息

爪哇 -

package webmodule;
import java.io.Serializable;

import javax.faces.application.FacesMessage;
import javax.faces.application.FacesMessage.Severity;
import javax.faces.context.FacesContext;

import model.User;

import org.omnifaces.util.Faces;
import org.springframework.beans.factory.annotation.Autowired;


 public class Userweb implements Serializable 
 {

User bindUser;

@Autowired
public void setBindUser(User bindUser) {
    this.bindUser = bindUser;
}

public User getBindUser() {
    return bindUser;
}

public void saveUser() throws Exception {
    String result = null;
    FacesMessage msg = new FacesMessage("Done", "It worked");
    FacesContext.getCurrentInstance().addMessage(null, msg);


    //return result;
}

 }

但是，如果我删除autoUpdate并使用以下，那么它可以工作 -

<p:ajax event="click" listener="#{userweb.saveUser()}" update="msgs" />

我正在使用 - Primefaces 4.0 jsf 2.2.6（mojarra） Tomcat 7

Plz帮帮我.....谢谢

Answer 1

通过将JSF 2.2.6降级为JSF 2.2.2，一切都开始起作用。
