On Event Changed

when i want to update my already exiting event
i used this method for updating my event

 scheduler.attachEvent("onEventChanged", function(id,data){

but first oneventSave method is calling and saving the both updated event + already exiting event with previous data.
i used this method for Saving my event

scheduler.attachEvent("onEventSave", function(id, data) {

i want to update my event only.

Currently onEventSave doesn’t provide info about state of event , it will be the same for updated and newly added events.

In oncoming scheduler 2.3, it will have extra parameter to separate new and existing events.

Understand ur thought , But i Am using different services for create and update event , this is causing real problem for me . For this I need to determine the event status whether its new or existing one before calling respective service .
let us know ur thoughts , urgent…
