"MODIFICATION_FAILED" with Lightning / Rainlendar 3 Months ago  
Hi,

I'm using the combination Rainlendar and Lightning to manage iCS based calendars. I have a problem with alerts generated by Rainlendar. Rainlendar uses the "ACTION:AUDIO" in the event. Lightning instead uses "ACTION:DISPLAY".

If the iCS calendar contains events/tasks with a reminder defined in Rainlendar (with the "ACTION:AUDIO" statement), the modification (adding/deleting/changing events) with Lightning will fail with the error message "MODIFICATION_FAILED". The calender can only be used as read only in Lightning in such a case.

After replacing "ACTION:AUDIO" with "ACTION:DISPLAY", the calendar is modifiable with Lightning again.

In Rainlendar's advanced options, I've already checked the option to create Mozilla compatible alerts. It would be very nice if these alerts would really be compatible. Could you please fix this?

==== Used Versions ====

OS: Windows 7 x64 SP1

Has there been some changes in Lightning? I don't remember seeing this kind of problem before. The "Mozilla compatible alarms" setting just sets the acknowledge information the same way as Lightning does so you don't have to dismiss the alarms twice. The problem with the DISPLAY actions is that it doesn't support attachments which Rainlendar uses for custom sounds.

Hi,
thank you for your quick response.
I don't know about any changes in Lightning considering alerts. I can't tell you since when the problem exists. In almost all cases I'm using Rainlendar to manage my events.
Since I don't use a sound notification for my alerts I didn't notice any additional entries for custom sounds.

As a workaround, I'll set reminders in Lightning now, not in Rainlendar anymore. This works fine.
