DSE: Opening a schedule generates a change in the model
To reproduce:
- generate some schedules with DSE
- save
- open a schedule
—>the model is now marked as dirty (i.e., with a little star close to th ename) indicating it is different from the saved version, but it should not be so: the model did not change, only the schedule was open.
