Outlook add in (calendar event): Recurrence is always null

Question

I have an Outlook addin for calendar events, with a task pane. From the pane, I get the event data:

   date start: item.start.getAsync()
   date end: item.end         


        

Answer 1

With the code you gave me in the comment, i get the recurrence when it changes:

  Office.context.mailbox.item.addHandlerAsync(Office.EventType.RecurrenceChanged, handler, callback);

But only 'handler' function is called, where the recurrence is valid: console.log(JSON.stringify(eventarg.recurrence));

• Why callback function is not called?
• Why I can not get the recurrence with my function:

Office.context.mailbox.item.addHandlerAsync(Office.EventType.RecurrenceChanged, handleRecurrenceChange);

In this case, handleRecurrenceChange is called but when I call item.recurrence.getAsync() i get result.value = null

The same if I call item.recurrence.getAsync() when I need the recurrence (I get null)

I would like to get the recurrence when I need it (I can get all other event values properly), without saving it when changed, if possible...
