We have extended the event-calender with extra filters according to this tutorial: http://doc.silverstripe.org/doku.php?id=recipes:extending_the_event_calendar&s=dropdownfield%20cms%20editor
We would like the datefilter on frontend to set default dates to "today" as starttime and "today + 1 month" as endtime, (ie: Start: 25. Nov 2009 End: 25. Dec 2009 )instead of "today" as both start and end as it is now.
The start/end filters take default values that represent the current view, so if you want the end date to show today, and the end date to show today +1 month, then range for your calendar view has to be today - today+1 month. So probably the easiest thing to do would be to create an index() function to redirect to that range.
