Primefaces客户端Bean验证不起作用 [英] Primefaces client bean validation not working

问题描述

我正在使用Primefaces客户端bean验证，但是它不起作用，错误消息消失了.即使验证失败，也会调用侦听器.

I am using Primefaces client bean validation but it is not working,error messages disappears.Listener is called even when validation fails.

Java-

import java.util.ArrayList;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Set;

import javax.faces.bean.ManagedBean;

import org.hibernate.Criteria;
import org.primefaces.event.SelectEvent;
import org.primefaces.model.DefaultTreeNode;
import org.primefaces.model.LazyDataModel;
import org.primefaces.model.SortOrder;
import org.primefaces.model.TreeNode;

@ManagedBean(name = "myBean")
 public class MyBean {



Car selCar;

public Car getSelCar() {
    return selCar;
}

public void setSelCar(Car selCar) {
    this.selCar = selCar;
}



public MyBean() {


    selCar = new Car();


}



public void callMe(){
    System.out.println("Hi");
}

 }

Car.java-

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.validation.constraints.Size;

import org.primefaces.component.export.Exporter;

@Entity
public class Car {

@Id
String id;

@Size(min=1,max=2)
String name;


public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

}

但这有效-

    <p:commandButton  value="Click Me" validateClient="true" action="#{myBean.callMe}">

调试之后，我发现调用侦听器时会显示消息，但一旦完成，消息就会消失.

After debugging i found out that when listener is called messages get displayed but once it completes message disappears.

我正在使用- Primefaces 4 JSF 2.2.6(Mojarra) tomcat 7

I am using- Primefaces 4 Jsf 2.2.6(mojarra) tomcat 7

请帮帮我.谢谢.

推荐答案

一切都通过将JSF 2.2.6降级到JSF 2.2.2来开始进行.

Everything started working by downgrading JSF 2.2.6 to JSF 2.2.2
