Question

我正在努力让Deltaspikes @WindowScoped与TomEE合作（尝试过1.5.2,1.5.3-SNAPSHOT和1.6.0-SNAPSHOT）

这是一场非常小的战争，拥有deltaspike 0.4核心+ jsf依赖。

现在，我确实创建了一个像这样的HelloWorldBean：

@Named("HW")
@WindowScoped
public class HelloWorldBean implements PassivationCapable,Serializable{

    private static final long serialVersionUID = 1L;
    private String name;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    @PostConstruct
    public void test() {
        System.out.println("Bean did get constructed");
    }
....
}

有一个空的beans.xml，空的faces-config.xml和一个非常小的web.xml。

在一个非常简单的页面上。

<h:form>
           <h:inputText value="#{HW.name}"></h:inputText>
       <h:commandButton value="Welcome Me" actionListener="#{HW.printIt}"></h:commandButton>
        </h:form>

页面工作正常，windowId被添加到请求中，当我刷新页面时，我看到bean没有实例化（即test（）只被调用一次）。但是，一旦我按下commandButton，我就会得到一个ContextNotActiveException异常：

我错过了一些明显的东西吗？或者它是DeltaSpike中的错误？（或TomEE？）

此异常表示未在WindowContext中设置windowId。您是否在片段中添加了正确的DeltaSpike标签？

ds：windowId部分很重要。您可以调试DeltaSpikeLifecycleWrapper #execute以查看windowId是否被正确检测到。

Deltaspikes @WindowScoped与TomEE合作？
