Hi all, I'm writing a client for the CalendarServer and hit a small snag. I'm testing the outcome via Calendar app on OS X.

I can PUT vcalendar items with rrule to the server and they come out correctly.
I can PUT a recurrence with a changed DTEND to the server and it comes out correctly.

When I add an ATTENDEE to the recurrence however I have problems.

If I do it via the calendar app I can see that it triggers this after the put:
"implicit REQUEST - organizer:..."
and the attendee gets a copy of the vcalendar. 

When I run my put request however this does not happen. The contents of the requests are identical but is there anything special I need to do to trigger this?

I might be missing something in the headers?

Here is my post-data to create a recurrence with changed DTEND and ATTENDEE
