Question

我正在使用Primefaces客户端bean验证，但它无效，错误消息消失。即使验证失败，也会调用Listener。

的Sample- xhtml-

    <h:form id="parentForm">

        <p:inputText value="#{myBean.selCar.name}"></p:inputText>
        <p:commandButton  value="Click Me" validateClient="true">

            <p:ajax event="click" listener="#{myBean.callMe}"
                 update="msgs" process="@form"></p:ajax>

        </p:commandButton>


    </h:form>

</h:body>

爪哇 -

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}">

调试后我发现，当监听器被调用时，会显示消息，但一旦完成，消息就会消失。

我正在使用 - Primefaces 4 Jsf 2.2.6（mojarra） tomcat 7

请帮帮我。感谢。

Answer 1

通过将JSF 2.2.6降级为JSF 2.2.2

，一切开始起作用

Primefaces客户端bean验证不起作用
