我在 p:tabView 中遇到了一个问题，其中 dynamic="true" 我被困了好几天。我有三个选项卡，每个选项卡都有单独的表单和 p:fileUpload 带有用于提交表单和上传文件的命令按钮。问题是我的第一个表单或选项卡工作正常，但其他两个根本不工作或触发命令按钮操作，而是刷新页面。只有在第二次填写表格并按下按钮时才会调用它们。并且要再添加一件事，fileUploadListeners 甚至在所有这些选项卡中都可以正常工作，但是命令按钮将无法工作或触发其他两个选项卡的操作方法（只有第一次填写并提交之后才能正常工作）：
这个primefaces标签有什么问题（我也使用最新版本的primefaces 3.5）还是我弄错了或遗漏了什么？任何类型的指导都会有所帮助。
这是另一个主页中包含的页面代码：
