We have an event with 3 parts. On the event detail page it looks like this atm (see screenshots)
Only the last date is not shown in the calendar. we have not tested other situations (i.e. more dates) yet. This seems to be a bug!
i have just done another test with en event over a span of 4 days. 2 days in may and 2 in april. both of april are not shown in the calendar view (=screenshot#2)
