堆栈跟踪有助于理解原因。此外，还介绍了JSF和CDI impl/version。顺便说一句，您当前形式的问题意味着当您删除RequestContext行时，问题不再发生，这很奇怪。你能再确认一下吗？我是客人，从堆栈跟踪来看，它是JSF2.2.8。我不知道如何查看CDI版本堆栈跟踪：好的，这是WildFly 8.2。这根本不是由RequestContext引起的。删除该行时，您将面临完全相同的问题。更重要的是，在任何任意UIInput值和UICommand操作上都会面临完全相同的问题：发现这是一个范围问题：我使用javax.faces.bean而不是javax.faces.view来处理这个MB。这是WildFly 8.2决赛。这就是CDI 1.2。看到了！非常感谢。
