Question

我认为这很简单，但我对此感到困惑。想法是想使用liferay wizard，如：https://www.primefaces.org/showcase/ui/panel/wizard.xhtml。我在xhtml上有这个：

<h:form id="frmCreate">
    <p:wizard flowListener="#{flowWizard.onFlowProcess}"> 
        <p:tab id="header" title="Header">
            <p:panel>
                /*1*/
            </p:panel>
        </p:tab>

        <p:tab id="detail" title="Detail">
            <p:panel>
                /*2*/
            </p:panel>
        </p:tab>

        <p:tab id="confirmation" title="Confirmation">
            <p:panel>
                /*3*/
            </p:panel>
        </p:tab>
    </p:wizard>
</h:form>

在豆子上：

@ManagedBean
@ViewScoped
public class FlowWizard {
    public String onFlowProcess(FlowEvent event) {
        return event.getNewStep();
    }
}

但是当我尝试单击“下一步”按钮时，它不会将页面更改为下一个选项卡，并且我在控制台上收到此错误消息：

怎么了？感谢。

堆栈跟踪建议您需要在Serializable

实施FlowWizard

java.io.NotSerializableException：com.wings.marketingevent.util.FlowWizard
