未调用 JSF Action（一种情况有效，而第二种情况无效）
Posted
技术标签:
【中文标题】未调用 JSF Action（一种情况有效，而第二种情况无效）【英文标题】：JSF Action not called (one case works while the second one does not) 【发布时间】：2015-10-14 20:59:40 【问题描述】：我在使用 p:commandButton 执行 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。我剪掉了一些实际上确认我的数据被保留的日志行。

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。因此，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很重要的附加标签。

这个 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，它不包含 h:form，因此没有嵌套表单。
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,

log.debug("Registration saved by user " + userEmail + " and customer number " + customerBean.getCustomernumber());

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
【问题讨论】：
你正在使用 Spring...为什么不将它添加到标签中？ 您能否将整个表单附加到您的帖子中？ 我更新了spring信息和上面的tag（感谢提示），下面贴出了我的xhtml文件。 【参考方案1】：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......
最好的问候
【讨论】：
你怎么知道 OP 正在使用 remoteCommand？问题中的任何地方都没有说明（无论如何我都可以看到）。是否有一些文档说明您在此处获得的此信息作为答案？以上是关于未调用 JSF Action（一种情况有效，而第二种情况无效）的主要内容，如果未能解决你的问题，请参考以下文章
如果关联组件未呈现，是不是可以调用 JSF Bean 的 Setter？
JSF2 commandButton 操作未在更新的片段中调用
