Resource Plans on Project Tasks do not move dates as expected with the Project Task - Known Error

Resource Plans on Project Tasks do not move dates as expected with the Project Task Description When the "com.snc.project.date_change_cascade" System Property is set to True Changing the 'Planned start date' from a Project Task Form is not updating the Resource Plan Dates for that Project Task.

Steps to Reproduce

1. Ensure that "com.snc.project.date_change_cascade" System Property is set to True 2. Create a Project 3. Create a Project Task on the Project 4. Create a Resource Plan on the Project Task level 5. Go to the Project Task Form View 6. Set the Planned start date to next month 7. Save the record 8. See that the Resource Plan Dates do not change

Workaround This is expected behavior and by design in all currently supported releases.
