>How have you created your DataView? How have you made it read only?

I was just using a parameterized SQL PT for now (I plan on converting to use a call to a SQL SP after I get this working). I'm using the GetDataSet() method in a class derived from mmBusinessObject. I'm passing in the string containing the SQL command and the IDbDataParameter[] parameter list array.

The field it's complaining about is calculated from a UDF call on the SQL server side. This seemed to work OK until I upgraded to the latest beta (but I have also made some other changes, so it's probably something I have done and not MM). The code to generate the DataSet is found in a parent class of the business object. I don't think that should be a problem.

I'm not trying to update any data in the DataTable or the DataSet.

Any ideas oh wise one?
