Question

我得到IllegalStateException已经在视图中找到了组件ID表单，我不确定是什么导致了这个问题，我首先不想要这个例外。

异常

我的xhtml页面如下：

        <link rel="stylesheet" type="text/css" href="/xmlhttp/css/rime/rime.css"/>
    </h:head>
    <h:body>
             <h:form id="form">
                <h:outputText value="Welcome to ICEfaces 3, select current date: "/>
                <ace:dateTimeEntry renderAsPopup="true">
                    <f:convertDateTime pattern="MM/dd/yyyy" timeZone="Canada/Mountain"/>
                </ace:dateTimeEntry>
                <ace:fileEntry id = "fileUpload"
                               label="File Entry"
                               relativePath="uploaded"
                               fileEntryListener="#{fileUpload.uploadFile}"/>
             <h:commandButton value="Upload File" />
             </h:form>
    </h:body>
</html>

所有我想要做的只是让fileUpload功能正常工作，奇怪的是，javascript文件夹中存在的css和javax.faces.resources内容未在应用程序中引用所以我得到了一些奇怪的错误。

另外需要注意的是，如果我将eclipse与icefaces插件一起使用，那么fileUplaod功能可以正常工作，但如果我尝试构建它们而不使用插件并且只使用标准的必需jar集我得到的组件ID相关IllegalStateException。

有什么想法，建议吗？

当我将javax.faces.PROJECT_STAGE设置为Development时，我使用mojarra得到这样的错误。如果您有此设置，请将其更改为生产，并查看错误是否消失。

我虽然知道bug但却找不到任何东西。
