Facelet标题

功能：

在这里，我们从index.xhtml导航到“register”流范围，其中包含register.xhtml、register-flow.xml、confirmation.xhtml

从register.xhtml导航到confirmation.xhtml

问题：

1）我想在confirmation.xhtml中创建一个“back”输出链接，以导航回register.xhtml

<h:outputLink value="register.xhtml">
                 <h:outputText value="back"></h:outputText>
             </h:outputLink>

但这不起作用，当我点击UI上的“后退”时，会出现以下错误

“WELD-001303:作用域类型javax.faces.flow.FlowScoped没有活动上下文”

有趣的是，

正在工作

2）为什么我们不能直接在目录（“register”）中运行文件。它给出了以下错误： WELD-001303:作用域类型javax.faces.flow.FlowScoped没有活动上下文

我很困惑。请帮帮我
