When a user refreshes a Gantt chart and then attempts to modify a Task date for example, the date does not get changed.
STEPS TO REPRODUCE:
1. Open a project
2. Click on Tasks
3. Open Gantt view
4. Refresh Gantt view
5. change “Start Date” in a task
Expected Results: Start Date and End Date changes to the new dates and the old dates are displayed in red.
Actual Results: Start Date and End Date stays the same.
This behaviour was reported to Engineering via DE60105.
Release : 15.8.1
The defect was closed as "Could Not Reproduce (CNR)", in version 15.9.2. It has however been noticed in version 16.0.1 as well, but works fine in 16.0.2 (the latest version as of this writing).
Try to change the date again the second time and this will get changed.
