you could do using data model but easier way is to adjust calendar using client side customizations http://livedemo.exadel.com/richfaces-demo/richfaces/calendar.jsf?tab=clientSideCustomization&cid=1540131
Hi Ilya, thanks for your reply!
This example only shows the disablement without using a bean. But i don't understand how to combine two calendars. I want that a selection in calendar 1 has an effect in calendar 2. Do you have a code snippet for this?
