Created attachment 152961 [details] Screenshot of error message SUMMARY *** When creating a new event fails (because of calendar backend problem), only error message is shown, event discarded *** STEPS TO REPRODUCE 1. Have a calendar synced to some cloud, but the backend is unavailable or something is wrong with it. 2. create a new event for that calendar. 3. Click "Add" in the Add Event dialogue. 4. I get an error message saying "Error creating the calendar entry. Error message is "Invalid parent collection". 5. Hit OK on that. The "Add Event" dialogue is gone. OBSERVED RESULT I spent a few minutes typing in the details of that event, maybe searching the location on the map, editing the description, adding reminders etc. Now, because of the backend error, I have to type it all again, the information is gone. EXPECTED RESULT I get notified of the backend error, but the "Add Event" window stays open. Ideally, I get to opportunity to save it locally, even though it cannot be synced to the cloud. I get the chance to investigate the backend problem without having to retype everything when it's fixed. Instead, the locally saved event would just get synced at the next opportunity. Else, I can choose a different calendar/backend to save the event to.
