Should Grid Spread Work when Accessing Forms through SmartView?

Summary:

I have created a form using IDescendants(Full Year) and I have checked the "Enable Grid Spread" box. When accessing the form through the PBCS application, I can enter a lump sum into the Full Year cell, and the application will spread 1/12 of that value to each month.

When I access the same form via the SmartView, the Full Year cell is editable, but when I submit the data the value in the cell disappears on submit.

Is grid spread supposed to work in SmartView the same way it does in the application's Data Forms?

Thanks in advance!
