jsf-2 primefaces download

Jsf 2 p:fileDownload不与h:head一起工作,jsf-2,primefaces,download,facelets,head,Jsf 2,Primefaces,Download,Facelets,Head,我有这样一个： <h:form id="form1"> <p:commandButton id="downloadLink" value="Download" ajax="false" onclick="PrimeFaces.monitorDownload(start, stop)" icon="ui-icon-arrowthichk-s" actionListener="#{search.downloadActionListener}">

我有这样一个

：

它不起作用。“下载”按钮只是重新加载页面，不显示“另存为”对话框。在检查了每一件事之后，我知道如果我从页面中删除

标记，它就会开始工作

如果没有

，我就无法工作，因为PrimeFaces的外观和所有ajax功能都依赖于它

更新：使用

生成的HTML

如下所示：

项目
的HTML输出表明您将PrimeFaces与ICEfaces混合在一起。具体问题的主要原因是来自ICEfaces的脚本：
<script src="/Project2.0/javax.faces.resource/icefaces-compat.js.xhtml" type="text/javascript"></script>



。这还包括下载按钮。但是不能使用ajax下载文件
完全清除冰面。你不需要它。但是如果你已经在使用PrimeFaces3.x，那么ICEfaces完全没有额外的价值。也许这是以前对各种JSF组件库进行实验的遗留问题
另见：




与具体问题无关，HTML输出还表明运行时类路径中也有RichFaces。虽然从理论上讲，这可以很好地与PrimeFaces配合使用，但我不建议将它们混合使用。RichFaces本质上没有PrimeFaces没有提供的东西。
比较两个HTML文档的标题，看看工作页面和非工作页面是否缺少/覆盖了任何内容。我检查了两个不同的HTML。我无法理解这一点，因为我对JSF和web开发还是新手。“它基本上是一个克隆”。没错，哈哈，非常感谢你的详细解释。实际上，我正在使用icefaces的fileupload标记，我发现这比primefaces标记更容易。我想我现在必须使用primefaces文件上传。
