In service release .2086 I could call updateGrid and everything worked fine.

In service release .2113 when I call updateGrid I now get an error.  The column it is complaining about has data as can be seen in the record dump below the error

1. Uncaught TypeError: Cannot set property 'PatientLastName' of null infragistics.datasource.js:36
