Control test
Cube1:
Attr A
Report1
Possible values of element prompt on attr
A being displayed for selection: X1, X2, X3
Select X1: X1 is displayed in grid.
No selection: X1, X2 and X3 are displayed in grid.
Attr A in both cubes is the same; mapped to the same MSTR attribute.
Result is expected
Cube2:
Attr A
Report2
Possible values of element prompt on attr
A being displayed for selection: Y1, Y2, Y3
Select Y1: Y1 is displayed in grid.
No selection: Y1, Y2 and Y3 are displayed in grid.

Negative test
Document:
1) Add Report1 then followed by Report2 as datasets.
2) Add 2 grids in document; 1 for each dataset.
3) Run document.
Possible values of element prompt on attr A being displayed for selection: X1, X2, X3
Select X1: X1 is displayed in both grids.
No selection:
X1, X2, X3 are displayed in grid1.
Y1, Y2, Y3 are displayed in grid2.
Result is not what I expected:
1) Was expecting X1, X2, X3, Y1, Y2, Y3 as selection since both datasets are primary datasets.
2) When a selection is made, that selection is displayed in both grids. This is weird.
3) When no selection is made, the elements of the attribute displayed are from the respective cubes. This is also weird.
