结束对话作用域 bean,然后在单击命令按钮时重定向
我有一个简单的命令按钮
<h:commandButton value="Create Form Event" action="#{formEventController.createFormEvent}"/>
,它调用以下简单的操作侦听器
@Named
@ConversationScoped
public class FormEventController implements Serializable
{
@Inject
private Conversation conversation;
...
public String createFormEvent()
{
conversation.end();
return "events?id=" + form.getId() + "&faces-redirect=true";
}
}
,所以基本上我想要一个按钮,单击该按钮将结束对话,然后重定向到新页面...
这有效一次,然后每次在我看到以下内容后我的日志..(从用户的角度来看,一切正常..单击按钮时,重定向正常工作)

I have a simple command button
<h:commandButton value="Create Form Event" action="#{formEventController.createFormEvent}"/>
which calls the following simple action listener
@Named
@ConversationScoped
public class FormEventController implements Serializable
{
@Inject
private Conversation conversation;
...
public String createFormEvent()
{
conversation.end();
return "events?id=" + form.getId() + "&faces-redirect=true";
}
}
so basically I want a button that when clicked will end a conversation, and then redirect to a new page...
this works ONCE, then every time after I see the following in my logs.. (from the users point of view, everything worked properly.. when the button is clicked, the redirect works properly)
