Stan,

>I get the following error when trying to use MyObject.SaveDataSet (MyDataTableName.TableName) to update the database after several deletions on the datatable: "Deleted row information cannot be accessed through the row."
>I only get the error if I have rules that are being validated as broken rules or warnings. I am using MM 2.2 ver where Entity classes are used and the actual Exception is triggered when entity values are addressed.

It sounds like you have ImmediateDelete set to false for your business objects. Check out the MM .NET Dev Guide topic "ImmediateDelete: Immediately Deleting from the Database". It shows you how to get around this issue in your rule code.

Best Regards,
