t:inputFileUpload 从mapped(pretty faces) .xhtml 页面调用时不起作用

Question

我正在使用 Tomahawk 库进行文件上传。 但是，当我单击 h:commandButton 提交表单时，永远不会调用支持 bean 的方法。

下面是应该完成这项工作的代码序列，它是 user_profile.xhtml 页面的一部分（存储在 WebContent 文件夹的根目录中；应用程序部署在 JBoss 6.1 上）：

<p:dialog widgetVar="avatar" hideEffect="fade" width="300" height="300"
    header="Avatar upload">
    <h:form enctype="multipart/form-data">
        <t:inputFileUpload value="#{uploadBean.uploadedFile}" id="upload" />
        <h:commandButton value="Upload" action="#{uploadBean.submit}" />
    </h:form>
</p:dialog>

提供对该页面的访问的链接是http://localhost:8080/user/20，因为在 Pretty-config.xml 文件中设置了 url 映射，如下所示：

<url-mapping id="user_profile">
    <pattern value="/user/#{id}"></pattern>
    <view-id value="/user_profile.jsf"></view-id>
</url-mapping>

但是，当我直接访问页面时，通过避免 Pretty -配置映射， http://localhost:8080/user_profile.jsf，上传操作正常！ 所以，我想这与漂亮的面孔有一些冲突，或者我忽略了一些东西。

提前致谢！

Tomahawk 过滤器未正确注册（未定义调度程序）。应该这样做：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="YAS" version="3.0">

...

这解决了问题。
