persist: true not honored on EventModel and CrudManager?

[KAB]

Hi

Version 1.2.1
I cannot figure out how to control the attributes that are sent on the EventModel via CrudManager and sync.
The flag has no effect. Am I using it correctly?

edit: the following values are sent to the server e.g.: But how can I control which attributes are sent?

{u'startDate': u'2019-02-17T05:00:00.000Z', u'endDate': u'2019-02-26T05:00:00.000Z', u'name': u'Hans Peter', u'resourceId': 32, u'eventColor': u'orange', u'duration': 9, u'partner_id': 9, u'id': 48, u'reservation_id': 46}

 class Reservation extends bryntum.scheduler.EventModel {
        constructor(reservation) {
            super(reservation);

            var draggable = true;
            var color = "yellow";
            var resizeable = true;

            switch (reservation.reservation_state) {
                case "draft":
                    color = "orange";
                    draggable = true;
                    resizeable = true;
                    break;
                case "confirm":

Ok you can close it. The return statement is missing on
