Summaries and UltraCalcManager errors.
posted

I have a grid in my application with an unbound formula column that is a simple multiplication of two cells.  This column has a summary in the groupby row.  In my application, if the data is reloaded, the following error is produced:

An unhandled exception of type 'System.NullReferenceException' occurred in Infragistics4.Win.UltraWinGrid.v12.2.dll

Additional information: Object reference not set to an instance of an object.

If I remove the summary, the exception is not thrown.  I am using version 12.2.20122.2018.  I see quite a few posts similar to mine in nature, but most seem to indicate the issue should have been resolved in previous releases.

It is dependably replicated, so if you need a sample project I'm sure I can provide one.

Thanks for any assistance you can provide.  It is fairly important that I summarize this column.
