Tying Datasource to Grid Issue

[jvwiv]

Guys,

I have a form that was working fine prior to taking the upgrade, but now receive the error shown below.  I've recreated the form in steps and have recreated the point in time when the error occurs, when I create a data grid on the screen and attach it to the data source that utilizes the stored proc.  The data source (stored proc) runs fine until it's attached to the grid.  Once it's attached to the grid, the following error occurs.

 Any thoughts?
