我已经在Tomcat 7.0.42 + jdk1.6.0_27系统上将Mojarra 2.2.5更新为2.2.6,并且在启动时,我遇到了folloging错误(...即使应用程序启动并正常工作):

我有一个包含以下代码的 JSF 页面：

...
<f:event type="preRenderView" listener="#{page1.PreRenderViewEvent}"/> 
...

现在我需要在页面中而不是在Page1 类构造函数中注册侦听器（Page1.PreRenderViewEvent 方法）......类似于：

...
UIViewRoot root = FacesContext.getCurrentInstance().getViewRoot();
root.getListenersForEventClass(javax.faces.event.PreRenderViewEvent.class).add ....
...

我如何完成此代码？
谢谢。

我正在尝试将简单的 JSF2.2 原型从Mojarra 2.2.5（...工作正常...）迁移到MyFaces 2.2.3，但出现NullPointerException。我通常使用 Mojarra 做的是以编程方式
在容器中 包含（注入）JSF 页面。

<h:panelGroup id="container">
</h:panelGroup>
<h:form>
    <h:commandButton value="Include page" action="#{inclusion.include('included.xhtml')}" />
</h:form>

    <h:outputText value="INCLUDED TEXT ..." />

    @ManagedBean(name="inclusion")
    @RequestScoped
    public final class Inclusion {

    public void include(String contentUrl) throws IOException{
        FacesContext fc = FacesContext.getCurrentInstance();        
        FaceletContext f2ctx = (FaceletContext) fc.getAttributes().get(FaceletContext.FACELET_CONTEXT_KEY);
        UIComponent uic = fc.getViewRoot().findComponent("container");
        if (uic != null && f2ctx != null) {
            f2ctx.includeFacelet(uic, contentUrl);              
        }
    } …
