在一个jsf页面中，我从这样的烘焙豆中获取数据

<p:dataList value="#{userArtifacts}" var="art" itemType="artifact" type="inset">

我有一个 java.lang.StackOverflowError，

我的支持 bean 看起来像这样，我希望有一个生产者来缓存数据，然后可能会覆盖它......

我只想在 ViewAccessScope 期间维护列表

顺便说一句，如果将我的 Producer 更改为 SessionScope 我没有问题

@Named
@ViewAccessScoped
public class FArtifacts  implements Serializable{

@PostConstruct
public void init()
{
    artifacts= getArtifactController().getArtifact(15);
    System.out.println("[INIT] Get All Art");

}

@Produces
@ViewAccessScoped
@Named("userArtifacts")
public List<Article> getMyArtifacts()
{

    System.out.println("[CUSTOM] Return all");
    return  artifacts;

}

servlet 异常是：

javax.servlet.ServletException
    javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
    org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:62)

PrimeFaces 的旧版本会导致 Window-ID 参数出现问题。如果您使用的是新版本，您应该将问题报告给 PrimeFaces 团队。
