[OPEN] Drag and drop calendar feature for undated items requires browser refresh to show changes


Engineers are currently investigating the issue.


When dragging and dropping undated events into the calendar, all events disappear and the page requires being refreshed to see the events as well as the changes (newly dropped assignment)

Expected Behavior

Dragging the events should just place them within the calendar without the need for a refresh


No workaround exists at this time.

Steps to Reproduce

Prerequisites: Have an instructor enrolled into a course with multiple assignments without due dates

  1. Act as an instructor

  2. Access the calendar

  3. Make sure the course calendar is toggled, and click on “undated” in the bottom right to show all undated course items.

  4. Click on one of the assignments and drag it to any date in the calendar

  5. Notice that all events on calendar disappear. Refresh to see changes.
