Hello, we are updating an old .NET 3.5 WinForm application that used an old version of Infragistics .NET Advantage 2 to .NET 4.5 and Infragistics 4, and are occasionally getting a ArgumentNullException in UltraWinGrid.FormulaTargetRefBase. Stack trace follows:

We have an UltraWinGrid with a UltraCalcManager, a computed row, and a Group By feature. I suspect the problem is associated with the Group By as we can most often trigger the exception by rapidly toggling the Group By selection.
Hello,
This is not an expected result. Please attach your sample here and I will look it over to determine what is going wrong.
If you would prefer not to attach your sample on the public forum, please let me know and I will create a private case for you.
Upon further investigation, this may be because of the computed row; given the line:
this._ultraCalcManager.SetCalcSettings(this._ultraStatusBar, new Infragistics.Win.UltraWinCalcManager.CalcSettings("Test", null, "count ( [//_myGrid/Order/OrderNumber] )", "Text", Infragistics.Win.UltraWinCalcManager.CalcErrorIconAlignment.Default, null));
If I remove the line:
this._myGrid.CalcManager = this._ultraCalcManager;
I do not get the exception after toggling the Group By selection.
