I am banging my head looking at the code for ... quite some time.
I have a lightning event, created from ics (including an alarm). I want to delete the alarm after something has occurred. I found calItemBase has mAlarms. But how to delete a single alarm? (there should be only one). What is the proper value of mAlarms if there is no alarm? What to do with mAlarmLastAck and other properties?
My workaround is to recreate from ical without the alarm, but then the user looses categories and other things he set for the event in the UI.
Many thanks,
Klaus
