How to determine within lightbox if event is new or existing

Hello, is there a way to tell if an event is new or existing (i.e. will be created or updated by a save event) once the lightbox opens?

Thanks as always for a great product.

There is inner property

scheduler._new_event

which is set to positive ( not null ) value when currently processed event is newly created.

Also, you can check the event’s id. New events has timestamp as ID, which must be easily separable from saved events, which has valid int IDs.
