Im working on a calendar of events in which each event can be assigned multiple rooms. I was able to create a conflict when Event A with Room One has the same date and time with Event B with Room One. I did this with a rule component and comparing both fields. Works fine. The problem is that I dont get the conflict any more when one of the events has more than one Room assigned, lets say Event A has Room One and Room Two. The rule comparison does not work any more. In other words I need to check if any room(s) in Event A exist in Event B.
Any direction in how to accomplish this?
