我在使用 p:commandButton 的 jsf 操作时遇到了奇怪的行为。相应的页面负责一些创建和更新任务。因此，我可以使用空白表单访问该页面，或者继续使用已加载到表单中的一些已保存数据。未按预期工作的按钮会触发保存操作以保留表单信息。

现在这是我的问题：当我继续处理一些已保存的数据并单击“保存”时，一切正常。调用该操作并保留数据或显示验证错误。这是我通过登录 MyPhaseListener.afterPhase() 获得的一些日志语句。我剪掉了一些日志行，这些行实际上确认我的数据是持久的。

现在最重要的部分是当我保存新数据时，没有调用任何操作。所以目标不是更新现有数据，而是插入新数据，但是对于我的 JPA 层来说，这种差异比对于 JSF bean 更有趣。生命周期正常处理，但没有调用任何操作。

除了调用动作之外，它看起来非常相似。这就是我无法理解的。我单击完全相同的按钮并调用完全相同的操作。

这是我完整的带有 h:form 的 xhtml 文件。我稍微缩短了它。整个文件包含更多的输入字段（它们都遵循相同的模式）和一些仅对样式目的重要的附加标签。

此 ui:composition 包含在另一个带有布局信息的 xhtml 文件中。这个布局模板相当不起眼，它不包括 ah:form 所以没有嵌套的表单。

和我的（缩短的）jsf bean

@Component
@Scope("view")
public class TollRegistrationBean implements Serializable {

    ...

    @PostConstruct
    public void init() {

        // get registrationId by param and load registration
        RequestContext context = RequestContext.getCurrentInstance();
        String registrationId = (String)context.getCallbackParams().get(TollRegistrationMainBean.CALLBACK_PARAM_SELECTED_REGISTRATION_ID);
        if (registrationId != null && !registrationId.isEmpty()) {
            registration = tollPersistingService.loadRegistrationAndCheckFields(registrationId);
        }

        if (registration != null) {
            createAccordionOrder();
            selectedTolls = registration.getTollTypes();

            // update saved customer data, read from DB, with data from crm
            tollCustomerBean.loadCustomerDataFromCRM(registration);
        }

        activeIndex = 0;
        registrationSent = false;
    }

    public void saveRegistration(String currentAccordionStep) {
        log.info("TollRegistrationBean.saveRegistration()");

        try {
            tollPersistingService.saveRegistration(registration, customerBean.getCustomernumber());
            activeIndex = accordionOrder.indexOf(currentAccordionStep);
            registration.getStepByStepName(StepName.valueOf(currentAccordionStep)).setCssAccordionIcon("");

            FacesContext.getCurrentInstance().addMessage(null,
                    new FacesMessage(FacesMessage.SEVERITY_INFO, MessageUtils.getMessage("toll_registration_info_saved_successfully"), ""));

            String userEmail = UserUtils.getCurrentUser().getEmailAddress();
            log.database(AdvancedLoggerUtils.Actions.TOLL_REGISTRATION_SAVE.name(), registration.toDatabaseLogString(), userEmail,
                    AdvancedLoggerUtils.System.WEB.name());
            log.debug("Registration saved by user " + userEmail + " and customer number " + customerBean.getCustomernumber());
        } catch (Exception e) {
            log.error(e.getMessage(), e);
        }
    }

}

我正在使用 JSF 2.2、Primefaces 5.2 和 Spring 4.1.4.RELEASE。

有没有人遇到过相同或类似的问题？对于任何帮助或提示，我将不胜感激。我有点坚持这个。

感谢和问候塞巴斯蒂安

早上好塞巴斯蒂安，

如果 p:remoteCommand 仍在运行，则无法提交表单。你必须把它放在一个单独的表格中......

此致
