Priviet,
I have implemented my version of the organizer:
http://livedemo.exadel.com/richfaces-demo/richfaces/calendar.jsf?tab=organizer
Prekrasno.
I was interested in preloading not only the date in the displayed month.
Loading happens in:
public CalendarDataModelItem[] getData(Date[] dateArray)
preloadDateRangeBegin and preloadDateRangeEnd should works in client side mode.
