Suppose, I have Id column (Listbox) in application 1 and 2. In application 2 I select Id# 2 and save it and close it. (Means Application 2 has current selection as Id# 2)
Now when I make selection in Application 1 as Id#1 and check the apply state on top of current selection and on the button click open the application 2, Id in application 2 does not retain 2 as selection , rather 1 is selected.
So, what is the use of the option Apply state on top of current selection. Hope I'm clear.
If you select Apply state on top of current selection it will select the current selections in the new dashboard replacing the existing the selections. If you don't select that option Dashboard will load with default selections.
