OverlapCalendar loading error

Dear Experts,

Because the fiori version of my DEV environment is 1.28.28, so I have to use OverlapCalendar instead of PlanningCalendar.

I'm verifying OverlapCalendar in Web IDE, but there is error when loading page.

There is no error message in console and I found that CalendarRenderer.js can't be loaded.

sap.ui.define([    "sap/ui/core/mvc/Controller"
], function(Controller) {    "use strict";    return Controller.extend("Verification.controller.OverlapCalendar", {            onInit: function() {                var oEvent = new sap.me.OverlapCalendarEvent({                    startDay:"/Date(1464566400000)",                    endDay:"/Date(1464566400000)",                    type:"02",                    name:"testDate"    });                this.byId("id_calendar1").insertCalendarEvent(oEvent,0);            }    });
});

Is there anyone has clue about it?

Best Regards,

Chad
