When I set up some of our recurring events, I'm not sure when they might end as they are demand and funding dependent. It would be great if we could edit the end date after the event is set up.
I recently deleted an event that is due to end in January. I thought by selecting the last event and deleting that it would only delete the future events but sadly it deleted them all.
You're right, that at the moment there's a bit of a "functionality gap" around repeating events, in that once the repetition rules are all set up, you can't edit them. Your only option really is to recreate the event with new repetition rules.
This isn't too onerous though - if you find the first event, click Copy, then save with the new repetition rules, then delete the original.
Regarding deleting recurring events, I however suspect this was a slight case of user error (sorry!).
When I tried it just now on the test site, I went to delete one event from a set of recurrences, and was presented with the options of delete only this instance and delete all occurrences. The buttons behaved as expected!
PS. Thanks for demoing your site at the User Group meeting today! :-)
