Status: UNCONFIRMED

(Calendar :: General, defect)

Steps to reproduce:

Add a calendar (CalDAV in my case) on which you only have read permissions (without checking read-only in Lightning)
Switch to offline mode
Create an event on the calendar
Switch back online


Actual results:

Event appears in cached calendar, when switching back online, event is still displayed, despite the fact of a 403 from server
Lightning tries to synchronise the event on each sync run


Expected results:

When 403 is return, an error dialog should be displayed, indicating that permission was denied and asking if :
- creation should be retried (in case of temporary configuration error)
- event should be discarded
- creation should be retried on a different calendar

The same dialog should be used in online mode when a 403 is received since there is currently no feedback of the error (event is simply not created which is confusing for most users)
