Calendar not displaying the event in the Daily/Weekly View

[LukeTucker]

Version: v12.1p_2020-04-15/PowerEdition
Browser: Chrome v84, Edge v84 (Chromium) and Firefox 79

The Calendar Daily View (and weekly) does not display an event scheduled when going through the days in the Calendar.

Steps to reproduce the issue:

1. Open the Daily View, and go to the day that the event is scheduled.
2. Go to other days using the "Previous" and "Next" arrows.
3. Go back to the day of the event and see that the event is not displayed. Resizing the window horizontally always make the "invisible" events appear in the view. When going to other days and coming back, the event is not there again.

Source:

public class External implements EntryPoint {
@Override

public void onModuleLoad() {

Calendar calendar = new Calendar();

calendar.setData(CalendarData.getRecords());

calendar.draw();

}

}



CalendarData:

public class CalendarData {

private static CalendarEvent[] records;
private static Date today = new Date();
private static int year = today.getYear();
private static int month = today.getMonth();
private static int start = today.getDate() - today.getDay();

public static CalendarEvent[] getRecords() {
if (records == null) {
records = getNewRecords();
}
return records;
}

public static CalendarEvent[] getNewRecords() {
return new CalendarEvent[]{
new CalendarEvent(1, "Meeting", "Shareholders meeting: monthly forecast report", new Date(year, month, start + 2, 0, 0, 0), new Date(year, month, start + 2, 23, 0, 0))
};
}
}


The console shows the following warnings when opening the page:

We're not able to reproduce this against latest 12.1, and your build is 6 months old - please retest with the latest patched build of 12.1 from smartclient.com/builds.
