Exception using GridGroupingControl

[Administrator]

I'm using a GridGroupingControl in ASP.NET and setting it's data source to a DataView object (although, setting it to a DataTable gives the same error). The underlying table doesn't have any Expression columns but I keep getting the error below.
The DataSourceCachingMode is set to ViewState, but setting it to None or Session also seems to cause the same error.
Any ideas?
