I cannot get the iNotesCalendar control to work.
It works in a tearoom.nsf. But if I put the controls in normal mail.nsf I always get a blank calendar.
I can get JSON via a web browser. Looks like this:

My code is this:
<?xml version="1.0" encoding="UTF-8"?>
<xp:view
    xmlns:xp="http://www.ibm.com/xsp/core"
    xmlns:xe="http://www.ibm.com/xsp/coreex">
    <xe:restService
        id="restService1"
        pathInfo="/inoteslegacyjson"
        preventDojoStore="false">
        <xe:this.service>
            <xe:calendarJsonLegacyService
                viewName="calendarOutline"
                var="entry"
                contentType="text/plain"
                colCalendarDate="CalDateTime"
                colStartTime="StartDateTime"
                colEndTime="EndDateTime"
                colSubject="For"
                colChair="Chair">
            </xe:calendarJsonLegacyService>
        </xe:this.service>
    </xe:restService>
    <xp:br></xp:br>
    <xe:calendarView
        id="calendarView1"
        jsId="cview1"
        type="#{javascript:sessionScope.dateRangeActions_selectedValue}"
        storeComponentId="restService1"
        style="width:100%">
        <xe:this.summarize>
            <![CDATA[#{javascript:summarize = sessionScope.calendarFormatActions_selectedValue == "true";}]]>
        </xe:this.summarize>
    </xe:calendarView>
</xp:view>
				
                        
You'd like to present the calendar view as iNotesCalendar for a normal mail database which is based on mail.ntf.
Your question's example is designed for and works with the teamroom.nsf. It uses a specialized view "calendarOutline". All calendarJsonLegacyService's properties which start with "col" define the specific column names of this view. So, you can't really use this example to read a "normal" calendar view of a mail database.
Luckily, all
calendarJsonLegacyServiceproperties' default values are dedicated to the "normal" calendar view "($Calendar) | Calendar" of mail boxes.Change your code this way:
viewNameproperty to "Calendar"databaseNamewith value "yourServerName!!pathToMailDatabase.nsf"Your restService would look like this then:
