We are currently in the process of developing a booking/rota system utilising the latest build of the Kendo UI JQuery library and during internal testing we've spotted a bug in the creation of recurrence events within the scheduler control whereby "weekly" recurrences are created with numerous "gaps" in the scheduled events.
To re-create this is quite simple,
1. Create a page containing a Kendo Scheduler control and configure pretty much with defaults (but allowing for the creation of weekly recurrent events).
2. Navigate to a specific month - the one we've been using to reproduce is June 2020. (Don't think it matters which scheduler view you use).
3. Create a new event and set the recurrence rule to be:
4. Save the event.
You should see that most of the events are created, however for all but the first week in the recurrence the events that should be created on the Mondays and Tuesdays are missing.
I've done some digging around within the development console across a few different current browsers, and it looks to be a bug in the SchedulerDataSource "expand" method. If you add an event with a recurrence rule specified as follows:
and then call the "expand" method on the data-source to split this into multiple events, you'll see that you actually end up with 14 events returned, rather than the correct 20.
This functionality is fairly critical to our current project, so would appreciate any feedback/response as soon as possible please. Happy to provide further explanatory notes etc...if needed.
