我使用p：commandButton使用jsf动作遇到奇怪的行为。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页面，或继续加载到表单中的一些已保存的数据。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：当我继续保存一些已保存的数据并点击“保存”时，一切正常。调用该操作并保持数据持久化或显示验证错误。以下是我通过登录MyPhaseListener.afterPhase（）获得的一些日志语句。我剪切了一些实际确认我的数据被保留的日志行。

现在stange部分就是当我为新数据保存时，没有调用任何动作。因此，目标不是更新现有数据，而是插入新数据，但这种差异对于我的JPA层而言比对JSF bean更有意义。生命周期正常处理，但没有任何操作。

除了调用动作外，它看起来非常相似。这就是我无法理解的问题。我点击完全相同的按钮并调用完全相同的操作。
这是我的完整xhtml文件，其中包含h：form。我稍微缩短了一点。整个文件包含更多输入字段（它们都遵循相同的模式）和一些其他标记，这些标记仅对样式目的很重要。

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引人注目，它不包含h：表单，因此没有嵌套表单。
和我的（缩短的）jsf bean
@Component

public class TollRegistrationBean implements Serializable {
...

public void init() {
// get registrationId by param and load registration
RequestContext context = RequestContext.getCurrentInstance();

registration = tollPersistingService.loadRegistrationAndCheckFields(registrationId);
}
if (registration != null) {
createAccordionOrder();
selectedTolls = registration.getTollTypes();

tollCustomerBean.loadCustomerDataFromCRM(registration);
}

}
public void saveRegistration(String currentAccordionStep) {

我正在使用JSF 2.2，Primefaces 5.2和Spring 4.1.4.RELEASE。
有没有人遇到相同或类似的问题？我真的很感激任何帮助或暗示。我有点坚持这个。
谢谢和问候 塞巴斯蒂安
答案 0 :(得分：2)
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......
祝你好运
