Multi-Resource Shared Events

Events can be shared among resources. This can easily be the same resource type, like people in a shared work calendar scenario or different resource types, like aircraft and instructor in a flight training scenario where you'll have to schedule an instructor and an aircraft for a class which is the event.

Shared events will render correctly in the appropriate resource columns with drag & drop, validation across invalid dates and times will work out of the box. All you need to do is to add both resourceIDs to the event.
