Jsf 具有相同ViewScope bean类的多个浏览器选项卡或窗口

使用Payara服务器4.1.2.174和mojarra 2.2.15

我有一个简单的命名Bean，其作用域为javax.faces.view.ViewScoped

import java.io.Serializable;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.annotation.PostConstruct;
import javax.faces.view.ViewScoped;
import javax.inject.Named;


@Named
@ViewScoped
public class SimpleBean implements Serializable
{
    private final Logger logger = Logger.getLogger(SimpleBean.class.getName());

    @PostConstruct
    private void init()
    {
        logger.log(Level.SEVERE, "{0}.init()", this);
    }

    private String name;

    public String getName()
    {
        return name;
    }

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

    public String action()
    {
        logger.log(Level.SEVERE, "{0}.action()", this);
        logger.log(Level.SEVERE,"====================");
        logger.log(Level.SEVERE, "name: {0}", getName());
        logger.log(Level.SEVERE,"====================");
        return "submit";
    }
}

因此，我有一个带有表单的简单index.xhtml页面

<h:form>
  <h:inputText value="#{simpleBean.name}"></h:inputText>
  <h:link value="To submit" outcome="submit"/>
  <h:commandButton value="Welcome Me" action="#{simpleBean.action()}"/>
</h:form>

我们可以看到SimpleBean有两个不同的实例。然后我提交第一个选项卡的表单

Severe: solvo.ee.beans.SimpleBean@2adafd68.action()
Severe: ====================
Severe: name: First tab
Severe: ====================
Finest: Handling PreDestroyViewMapEvent
Finest: Destroying @viewscoped beans from view map: {simpleBean=solvo.ee.beans.SimpleBean@2adafd68}
Finest: Handling PreDestroyViewMapEvent
Finest: Destroying @viewscoped beans from view map: {}

如果我尝试提交第二个选项卡的表单，则提交存储的早期SimpleBean实例（solvo.ee.beans）。SimpleBean@49a86248)将不使用，取而代之的是ViewScopeContextManager将创建SimpleBean类的新实例，如日志中所示：

Severe: solvo.ee.beans.SimpleBean@4797f115.init()
Severe: solvo.ee.beans.SimpleBean@4797f115.action()
Severe: ====================
Severe: name: Second tab
Severe: ====================
Finest: Handling PreDestroyViewMapEvent
Finest: Destroying @viewscoped beans from view map: {simpleBean=solvo.ee.beans.SimpleBean@4797f115}
Finest: Handling PreDestroyViewMapEvent
Finest: Destroying @viewscoped beans from view map: {}

我已经检查了com.sun.faces.application.view.ViewScopeContextManager.copyViewScopeContextsFromSession方法的代码，据我所知，这种行为是正常的。 但是，如果我在bean中存储请求参数或其他重要数据，我将丢失它，因为在提交第一个表单后实例将丢失

有没有一种解决方案可以让bean主要与第二个选项卡相关联（在我的示例solvo.ee.beans中）。SimpleBean@49a86248)？

这似乎是Mojarra的一个bug，将在2.3.10中修复，根据本文：

从同一个线程来看，Payara似乎已经在不等待2.3.10版本的情况下应用了补丁。升级到修补过的Payara是否为您解决了问题？

您是否能够找到解决此问题的方法？我有完全相同的一个：可能重复的

Severe: solvo.ee.beans.SimpleBean@4797f115.init()
Severe: solvo.ee.beans.SimpleBean@4797f115.action()
Severe: ====================
Severe: name: Second tab
Severe: ====================
Finest: Handling PreDestroyViewMapEvent
Finest: Destroying @viewscoped beans from view map: {simpleBean=solvo.ee.beans.SimpleBean@4797f115}
Finest: Handling PreDestroyViewMapEvent
Finest: Destroying @viewscoped beans from view map: {}
