我正在尝试实施流程。问题是我没有设置我的flowcoped bean属性。一点都没！当我导航到流程中的下一个视图时，永远不会激活setter。我正在使用Mojarra jsf实现的2.2.13版本。
我使用“值绑定”设置值，即
<h:inputText .... value="#{individualRegistration.firstname}" .../>
我正在使用CDI，即@Named与@FlowScoped一起使用。
然后bean本身可见，因为我的导航按钮使用了flowcoped bean中定义的方法，我可以正常导航。
流程本身是以编程方式定义的，即@Produces @FlowDefinition
UIComponents包含在
中<h:form>
虽然它们进一步包含在表单中的一些样式div中。
导航到下一个视图（此时我希望更新bean），我正在使用
<h:commandLink .../>
我在Payara 4.1.172（基本上是Glassfish 4.1）。
非常感谢。被困了一个星期！
这是bean代码。
