所有@ViewScoped注释（JSF，CDI，OmniFaces）都像@RequestScoped

我正在使用：Wildfly 8.2，JSF 2.2（Mojarra 2.2.8），Omnifaces 2.1和java 7.

问题在于我创建了一些对象以及重新创建的每个请求（null）。 我也试过使用conversationScope，但同样的事情发生了。

使用sessionScope可以正常工作。

控制器：

@Named
@ViewScoped
public class Teste implements Serializable {

    private static final long   serialVersionUID = 1L;
    private Map<String, String> passwordReminderUsers;
    private String              key;

    @PostConstruct
    public void init() {
        if (!FacesContext.getCurrentInstance().isPostback())
            passwordReminderUsers = new HashMap<String, String>();
    }

    public void add() {
        passwordReminderUsers.put(key, "b");
    }

    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }
}

每次回发passwordReminderUsers为null，导致NPE。

查看：

    <h:form id="form-login" prependId="false">

        <h:inputText value="#{teste.key}" />
        <h:commandButton value="add" action="#{teste.add()}" />
    </h:form>

我做了一些测试，没有使用primefaces，f：ajax，还有其他几个，没有任何作用。

此代码：JSF view scoped bean: #{authenticator}显示重新创建bean的每个请求。

也许相关： 我们使用JSF 2.0并在几个月前更新到JSF 2.2。 我必须使用这些命名空间：

<ui:composition xmlns="http://www.w3.org/1999/xhtml" 
    xmlns:ui="http://java.sun.com/jsf/facelets" 
    xmlns:f="http://java.sun.com/jsf/core" 
    xmlns:h="http://java.sun.com/jsf/html" 
    xmlns:p="http://primefaces.org/ui" 
    xmlns:c="http://java.sun.com/jsp/jstl/core" 
    xmlns:pe="http://primefaces.org/ui/extensions" 
    template="/WEB-INF/templates/default.xhtml">

因为新的xmlns.jcp.org不起作用并开始破坏页面而不渲染jsf组件。

也许相关：我们使用JSF 2.0并在几个月前更新到JSF 2.2。我必须使用这些命名空间[snip]因为新的xmlns.jcp.org不起作用并开始破坏页面而不渲染jsf组件

这绝对是一个强有力的线索，你实际上没有使用JSF 2.2，但仍旧版本。如果在WildFly上运行时发生了这种情况，它应该已经提供了JSF 2.2，那么这意味着您的运行时类路径被多个不同的JSF版本污染，或者WildFly实例被修改。

它应该在库存和未修改的WildFly实例上正常工作。
