错误消息，即使我仍然需要使用f:metadata [英] Error saying I need to use f:metadata even though I do

问题描述

从JSF 2.1更新到2.2后，我开始收到以下错误消息:

After update from JSF 2.1 to 2.2, I start getting the following error message:

The metadata component needs to be nested within a f:metadata tag. Suggestion: enclose the necessary components within <f:metadata>

这有点奇怪，因为代码看起来像这样:

It's a bit weird as the code looks like this:

....
 <ui:composition template="./resources/templates/template_base.xhtml">

        <ui:define name="contentBody">

            <h:outputStylesheet library="css/table" name="tableContent.css" />
            <h:outputScript library="javascript" name="pagination.js" target="head" />

            <p:growl id="messages" autoUpdate="true" />

            <f:metadata>
                <f:viewParam name="topicId" value="#{topicBean.topic.id}" />
                <f:event type="preRenderView" listener="#{topicBean.init(true)}" />
            </f:metadata>

        </ui:define>

</ui:composition>
....

如果错误消息所指的元数据组件是f:viewParam或f:event，那么我确实将其/由f:metadata括起来.

If the metadata component the error message refers to is either f:viewParam or f:event, then I do have it/them enclosed by f:metadata.

关于我在做什么错的任何想法?如果将javax.faces.PROJECT_STAGE设置为Production，该错误不会显示，但是我想将其保留在Development中，直到完成为止.

Any ideas about what I'm doing wrong? The error does not show if I set javax.faces.PROJECT_STAGE to Production, but I would like to keep it in Development until I'm finished.

推荐答案

针对JSF 2.2报告了错误.不久前，我正在处理相同的问题.

Bug reported for JSF 2.2. I was dealing with the same issue awhile back.

您可能还希望远离f:viewActions.
