Question

ContextNotActiveException в простом Faces Flow с CDI

Привет всем!

Я нахожусь на простом уроке потока лиц ( Tutorial), но не могу решить следующую ошибку:

Я использую Wildfly 8.1.0 в качестве сервера. Есть ли какая-либо дополнительная конфигурация сервера, необходимая для FacesFlow/CDI? (После того, как я провел некоторое исследование... нет, по моему мнению.)

Signup.java

@Named
@FlowScoped(value = "signup")
public class Signup implements Serializable {

private boolean licenseAccepted;
private String name;
private String surname;
private String email;
...

Регистрация-flow.xml

<faces-config version="2.2" xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">

<flow-definition id="signup">
    <flow-return id="index">
        <from-outcome>#{signup.homeAction}</from-outcome>
    </flow-return>
</flow-definition>

Между прочим, мои страницы с поддержкой RequestScoped и друзьями работают отлично, только компоненты FlowScoped, что приводит к указанной выше ошибке.

Надеюсь, кто-нибудь может мне помочь. Заранее спасибо.

Во-первых, я пока не знаю причину, но я знаю, что это связано с CDI и @Named аннотаций. Просто измените это на javax.faces.bean.ManagedBean и назвал это. Важно импортировать правильную аннотацию, поэтому я пишу полное имя пакета:

@javax.faces.bean.ManagedBean(name = "signIn")
@javax.faces.flow.FlowScoped("signIn")
public class SignInBean implements Serializable {
  private static final long serialVersionUID = 1L;

  private boolean licenseAccepted;
  private String name;
  private String surname;
  .....
}

Держите тот же XML-файл

Помимо этого уведомления, что другие бобы могут держать @Named аннотаций. Я имею в виду, если у вас есть @ViewScope можно сохранить как @Named вместо @ManagedBean,

@Named("home")
@javax.faces.view.ViewScoped
public class HomeBean implements Serializable {
   ...
}
