[CalendarServer-users] Report query against CalendarServer always returns [] with "REPORT request body may not be empty" error

5 May 2011

      The server seems to be finding the request body to be empty, but it's not.
I'm trying to look up *all* events from my calendar (on the Darwin
CalendarServer) but am getting an empty set preceeded by the error "Request
body cannot be empty".
Here's the code:
<code>
            log.info("Filter: VEVENT");
            GenerateQuery gq = new GenerateQuery();
            log.info(printQuery(gq.generate()));
            gq = new GenerateQuery(null,Component.VEVENT);
            log.info(printQuery(gq.generate())); //prints good request

            CalDAVCollection col  = new CalDAVCollection();
            col.setHostConfiguration(calendarClient.hostConfig);
            col.setMethodFactory(new CalDAV4JMethodFactory());

col.setCalendarCollectionRoot("/calendars/__uids__/skris/calendar");
            List<Calendar> cals = col.queryCalendars(calendarClient,
gq.generate());
            log.info(cals);// this is empty
</code>

Here is the server output:
