Bob,

>How do I create an empty dataset? As I mentioned, I am just calling the NewEntity method of the BO, setting entity values and then calling the SaveEntity method. I am not saving from a session variable.

But aren't you storing the DataSet in a session variable and then passing it in the method call when saving? If the DataSet contains multiple rows between saves, it must be getting stored in session state somewhere along the line.

Best Regards,
