When I have 1 measure in the PivotGrid, the only cells that show are those where the measure has values.

When I have 2 measures in the PivotGrid, I see empty cells.  Is this a bug?

To reproduce it, use the xamPivotGrid Demo, choose Basic > XMLADataSource.

Create a pivotgrid from "AdventureWorks DW 2008 SE" Database with the "AdventureWorks" cube.  Use "Internet Order Count" and "Reseller Order Quantity" as measures and "Promotion End Date" as the dimension.
