Event argument "changedRecords" on actionBegin/Complete question

Within the actionBegin and actionComplete events when modifying a schedule event (args.requestType = "eventChange" or "eventChanged"),  args.data contains the updated event data, as expected.  The args.changedRecords also contains the updated event data.  Shouldn't this hold the original event data instead?

Having the original values may be helpful or necessary when updating the backend database.

Hi John,

The args.data property of the actionBegin has been deprecated. So, you can get the original event details as shown in the below snippet.

Sample: https://stackblitz.com/edit/llrnbm?file=index.js


var scheduleObj = new ej.schedule.Schedule({

    actionBegin: function (args) {

        if (args.requestType == "eventChange") {

            var originalEvent = scheduleObj.activeEventData.event;
