我正在添加richfaces fileupload组件，但是当我在组件中添加一个文件时，它给出了以下的删除

但是当我将el表达式更改为fileUploadListener="#{row.facesUploadActionListener.processFileUpload(this)}"时，它可以工作，但FileUploadEvent对象为空。
下面是我有fileupload组件的xhtml代码：

其中一个我在调试中注意到我没有从el上下文中获得正确的函数映射器。
答案 0 :(得分：1)
请确保您的fileUploadListener方法具有FileUploadEvent类型的单个参数，如RichFaces展示的fileUpload sample所示。
