Primefaces 计划不起作用

Question

我正在使用下面的标签来安排日历

<p:schedule id="schedule" value="#{scheduleController.eventModel}" widgetVar="myschedule">  

这里的问题是，只有当我在构造函数中初始化这个 eventModel 时，才会显示时间表……如果我在构造函数之外的其他方法中初始化它不起作用……任何人都可以帮忙..

这里的 eventModel 代码与 primefaces show case 一样

eventModel = new DefaultScheduleModel();  
    eventModel.addEvent(new DefaultScheduleEvent("Champions League Match", previousDay8Pm(), previousDay11Pm()));  
    eventModel.addEvent(new DefaultScheduleEvent("Birthday Party", today1Pm(), today6Pm()));  
    eventModel.addEvent(new DefaultScheduleEvent("Breakfast at Tiffanys", nextDay9Am(), nextDay11Am()));  
    eventModel.addEvent(new DefaultScheduleEvent("Plant the new garden stuff", theDayAfter3Pm(), fourDaysLater3pm()));

您可以在PostConstruct 方法中初始化您的日历。该方法将在调用类的构造函数后直接调用，并且所有@ManagedPropertys 都设置为1。

public class ScheduleController {

  @ManagedProperty
  private UserBean userBean; // + setter

  private ScheduleModel eventModel; // + getter

  private ScheduleController() {
    // do nothing here
  }

  @PostConstruct
  private void init() {
    eventModel = new DefaultScheduleModel();

    if (userBean.hasPermission("something")) {
      eventModel.addEvent(new DefaultScheduleEvent("one", date1, date2));
      eventModel.addEvent(new DefaultScheduleEvent("two", date2, date3));
    } else {
      eventModel.addEvent(new DefaultScheduleEvent("three", date4, date5));
      eventModel.addEvent(new DefaultScheduleEvent("four", date5, date6));
    }
  }

}
