我没有看到组件周围有任何

，代码中有吗？我没有冰面方面的经验，但我已经习惯了。带着

它需要装在一个盒子里

<h:form id="paramsForm" enctype="multipart/form-data">

文件上传需要多部分/表单数据enctype

大多数情况下未关闭的标签会导致该异常。检查xhtml，您可能会找到任何打开的标记

e、 g：任何打开的div或span..

从

h:form

中删除

enctype=“multipart/form data”

，如果没有它，应该可以正常工作。

我在JBoss 7.1服务器上遇到了这个问题。我有一个EAR项目，一些EJB项目和几个WAR项目。当我遇到问题时，我在EAR库中部署了icefaces罐子，但是当我把他们转移到使用ace:fileentry的WAR项目时，它开始工作。

我使用的是

而不是

你能给你的ice:form添加一个enctype吗？使用了enctype，但它没有做任何更改。如果你的

fileUploadListener

调用的很好，没有任何问题吗？这从昨天开始就给我带来了真正的痛苦。现在事情是这样的，我在服务器日志中没有看到任何东西，调试器也没有点击

fileUploadListener

。我有完全相同的问题，我的fileEntryListener从未被调用，您是否得到任何其他结果，或者切换到richfaces是唯一的选项？不，这不是这里的问题，此外，此异常本质上是随机的，与包含的一个css文件相关，如果我删除该文件，则不会出现此异常。我已尝试从

h:form

中删除

enctype

，但仍然无法正常工作，您能否发布完整的工作示例，以便我可以验证导致此问题的原因，这是真正的痛苦。

<h:form id="paramsForm" enctype="multipart/form-data">
