如果我使用高级文件上传器,那么一切都可以,但我需要简单的文件上传器,无法让它工作。我不知道怎么解决这个问题。有人能帮我解决这个问题吗?JSF和PrimeFaces之间可能存在版本不兼容问题。您会使用什么版本的JSF和PrimeFaces?顺便说一句,你没有在你的真实代码中错误地嵌套表单吗?@Tiny JSF 2.2和PrimeFaces 5。0@Tiny是的,实际上是嵌套表单,我没有看到。很抱歉提出了一个愚蠢的问题,但这是我第一次使用PrimeFaces。这不是PrimeFaces相关的问题。嵌套表单在HTML中无效。在深入研究产生HTML代码的服务器端语言之前,您可能需要花更多的时间学习基本的HTML。
