I don't have an answer to your specific question as I havn't looked specifically at that code change. However the developers guide section "Saving DataSets using Business Objects" under Data Access with MM.NET indicates the same method would be called when you use method SaveDataSet. That would lead me to believe it is still supposed to work. Have you stepped through this code to see if he is also creating the EntityList first?
