Scheduler : Timing problem with the loading of calendars and their representation in the month view

Hello,

In Scheduler, Sometimes I don’t have the calendar representation in the month view when loading.
Looking in the library sometimes the calendar in LocalData.prototype.getColor is undefined because the data in LocalData.prototype.calendars comes right after .

Explanations : (in codebase/scheduler.js)

LocalData.prototype.calendars = function (sync, force) {
            var _this = this;
            if (this.app.config.calendars == false) {
                if (sync)
                    return false;
                return webix.promise.resolve();
            }
            var cals = this.cals;
            if (sync)
                return cals;
            if (this.cals_ready && !force)
                return this.cals_ready;
            this.cals_ready = this.app
                .getService("backend")
                .calendars()
                .then(function (data) {
                console.log('myCalendarData',data);
                cals.clearAll();
                cals.parse(data);
                _this.setActive();

                return cals;
            });
            return this.cals_ready;
        };

LocalData.prototype.getColor = function (data, calendar) {
            console.log('calendar',calendar);
            data.$color = calendar ? calendar.color : data.color || "#01C2A5";
            data.$textColor = getContrastingColor(data.color || data.$color);
        };

give sometimes :

So how it possible to execute LocalData.prototype.getColor only when server data has arrived ?

Or shift the graphic representation in time ?

example that works :

Thanks
