How to use calendar eventStore in memory?

[[email protected]]

Hi,
I'm using extjs 6.5 and I'm trying to use 'Ext.calendar.panel.Panel'.
I have set a store with data and a memory proxy and this works fine, but when I try to set a eventStore or a eventStoreDefault with a memory proxy the system give me an error.
I need to use these store with a memory proxy so I can load them from code with loadData().

The error is:

EventSource.js:170 Uncaught TypeError: store.hasRangeCached is not a function

The code is:

var eventList = {
    "evts": [{
        "id": 1001,
        "calendarId": 1,
        "startDate": "2018-06-30T21:30:00.000Z",
        "endDate": "2018-06-30T22:30:00.000Z",
        "title": "Watch cartoons",
        "description": "Catch up with adventurers Finn and Jake"
}]
};

var eventsstore=new Ext.data.JsonStore({
//var eventsstore=Ext.create('Ext.calendar.store.Events',{
    id: 'eventStore',
    root: 'evts',
    data: eventList, // defined in event-list.js
    proxy: new Ext.data.MemoryProxy(),
    fields: ["id","calendarId","startDate","endDate","title","description" ],
    sortInfo: {
       field: 'StartDate',
       direction: 'ASC'
    }   
 });


Ext.define('CalendarStore',{
    extend:'Ext.calendar.store.Calendars',

    alias:'store.calendarstore',
    data:{calendars:
        [{
        "id":1,
        "title": "Disponibilità",
        "color": "blue",
        "hidden": "false",
        "editable": "true",
        "eventStore":"eventsstore"
        }]
    },
    proxy: {
        type: 'memory',
        reader: {
            type: 'json',
            rootProperty:'calendars'
        }
    },

   eventStoreDefaults: eventsstore
});


Ext.define('Test.view.calendar.CalendarWeekWindow',{
    extend:'Ext.window.Window',
    xtype:'calendar-week-window',
    
    requires: [
        'Ext.calendar.panel.Panel',
        'Test.store.Calendar',
        'Test.view.calendar.CalendarModel',
        'Test.view.calendar.AddCustomEvent'
    ],

    closable:true,
    resizable: false,
    draggable: false,
    modal:true,
    autoShow:true,
    defaults: {
        bodyPadding: 20,
    },

    width: 1200,
    height: 600,

    layout: 'fit',
    items: [{
        xtype: 'calendar',
        
        store:{
            type:'calendarstore'
        },

        model:'calendar',
        views: {
            day: {
                startTime: 0,
                endTime: 24
            },
            month:{
                xtype: 'calendar-month',
                firstDayOfWeek: 1,
                addForm:{
                    xtype: 'add-custom-event'
                },//Ext.create('Test.view.calendar.CustomEventForm'),
            }
        },
        timezoneOffset: 0,
        listeners:{
            close:function(panel){
                panel.destroy();
            }
        }
    }]
});

Any ideas on how I can solve this problem?
Thanks in advance.

I have the same problem! Is the problem resolved?

The short answer is that you can't at the moment. It wouldn't take a great deal of effort to make that happen though.
