I’ve discovered a couple of bugs in version 2.2.2

 FullCalendar calendar = FullCalendarBuilder.create().build();
 calendar.setWeekNumbersVisible(false);
 calendar.setLocale(Locale.US);
 add(calendar);
 setFlexGrow(1, calendar);

At first the calendar days were in English, after switching to another view and back, it looks like they’ve changed to what I’m guessing is Dutch. The setWeekNumbersVisible method doesn’t seem to work either.

I’ve created an issue for that: https://github.com/stefanuebe/vaadin_fullcalendar/issues/48

Please let us discuss there the details. :)
