Use 'wget' to get the .ics file from the web and check its content whether it has the UID or not (just search for 'UID'). Based on the error messages there are not set those, at least not on some (if not all) of the components. Let the author know to generate the .ics file in a correct format [1] (I hope they do not claim too old version of the standard).

The .ics file does *not* contain any UID field, so it is corrupt (w.r.t the standard). Buut, ... ;) the .ics file is displayed on e.g. Apple iPhones without errors. Furthermore the .ics file is provided by an institution which is not technically adept. These people don't care about Evolution, they only care whether the calendar can be displayed on their phones. Trying to convince them to fix their website feels like fighting a losing battle. The Result: 1) I cannot use Evolution with this website so I am driven away from Evolution. 2) Everybody who wants to try Evolution is put off if she sees that Evolution can't handle these files (they get the impression that the software on iPhone is superior to Evolution, even though the problem is in fact the faulty .ics file) Would it not be better to 1) display a warning that the .ics file is damaged and 2) try to display the VEVENTS, nevertheless? But maybe it is too much of an effort...? [On a side note, let me state that I feel it is a bug in Evolution that Evolution does display the error messages *only* in the log files. Regarding the GUI one gets the impression that the .ics file was imported just fine. Would you agree that this is a bug? Should I report it to the bug tracker?] Kind regards, Jay ___ evolution-list mailing list evolution-list@gnome.org To change your list options or unsubscribe, visit ... https://mail.gnome.org/mailman/listinfo/evolution-list

The problem is that evolution uses the UID (and eventually RID - recurrence ID) as an identifier of the event, thus it can operate with it in the UI, and even with the local cache. Is the calendar public, thus anyone can use it, or it's a semi-private calendar? Being it a public calendar maybe someone can look on it. All there matters is the version of the .ics file. The RFC I gave a link to describes version 2.0. Earlier versions didn't have the UID mandatory. Maybe a change in the On The Web calendar could be done to add artificial UID properties for older versions of the .ics files. > [On a side note, let me state that I feel it is a bug in Evolution > that Evolution does display the error messages *only* in the log > files.

Say you've 100 events in the .ics file. Each being affected by a different issue, some with missing UID, some with other issues. How would you report such issue to the user? Collecting all the errors and sending them all at once, cluttering the UI? The other thing is that with the On The Web calendars you usually do not have any way to influence the content, as in your case. I know it's no strong argument, I'm just thinking aloud. I agree that there could be a notice that not all events (tasks or memos) were shown from the .ics file (this answers one of my above questions too).

The first 3 lines of the .ics file are: BEGIN:VCALENDAR VERSION:2.0 PRODID:-//dhtmlXScheduler//NONSGML v2.2//EN So I assume it is an iCal v2.0 file with malformed entries. The calendar is semi-private, but I can send the entire file in a private email if that matters to you. > >> [On a side note, let me state that I feel it is a bug in Evolution >> that Evolution does display the error messages *only* in the log >> files.

Cluttering the UI should certainly be avoided. I would display an icon http://commons.wikimedia.org/wiki/File:Gnome-dialog-warning.svg next to the calendar in in the calendar list. (Like the one with the two arrows (left-right) which is currently displayed for all my calendars and for which I don't know the meaning.) Clicking or hovering over the icon should then display a message like "Malformed iCal file. This calendar may be displayed incompletely. Please see logfiles for a detailed description."

Hi, that's correct, they claim to be version 2.0, but the content is malformed. > The calendar is semi-private, but I can send the entire file in a > private email if that matters to you. Interestingly, saving the file and adding it as a custom On This Computer calendar shows the events (with a newly added UIDs by the backend). > (Like the one with the two arrows (left-right) which is currently > displayed for all my calendars and for which I don't know the > meaning.) It's the connection state of the calendar, whether it's connected and/or reachable. I agree that the change to the two-arrows icon is confusing for me too. > Clicking or hovering over the icon should then display a message like > "Malformed iCal file. This calendar may be displayed incompletely. > Please see logfiles for a detailed description." Anything like that may require API changes. As the local backend can cope with missing UIDs, I guess the read-only On The Web backend can safely add missing UIDs as well.

Hi, I did so, for 3.17.2+ [1] and 3.16.2+ [2]. It requires to cleanup ~/.cache/evolution/calendar// and restart evolution-calendar-factory, thus it'll pick the changes and will fix the calendar content on the fly. Still, the correct solution is to fix the calendar generator to produce also UIDs for the components.
