Bug description

I scheduled a new meeting inside of NC, invited 4 people and added a Talk conversation. The name of the event was correctly set as the Talk room name, the description added as well and all 4 attendees added to the room.
However, when adding another attendee via Mac OS X Calendar app, which is accessing my personal NC calendar through CalDAV, the new attendee shows up in the calendar entry inside of NC, but is not added to the Talk room.

Steps to reproduce

1. create meeting inside of NC, set title and description, add one attendee (in addition to self)
2. click on "Add Talk conversation"
3. verify the talk room is added and two attendees are set
4. refresh the Mac OS X calendar, the new meeting will appear with both attendees set
5. add another attendee in Mac OS X calendar and wait for it to be pushed back into the NC server
6. open the meeting in NC and verify the new attendee has been added
7. verify the talk room still lists only 2 attendees, the new attendee is not added

Expected behavior

the new attendee should have been added to the talk room

Thank you for the feedback, @ronnybremer.

This feature doesn't exist this way. Only the Calendar frontend pushes event attendees as Talk participants. Changes done with a local client do not trigger such automatism right now.

That explains it, thank you @ChristophWurst! Can and shall I turn this into a feature request?

[ChristophWurst]

Yes please
