Mike,

>I'm finding that .AutoIncrementCustom doesn't take affect until after the physical table is "touched". Specifically, if I call myBusinessObject.NewRow() before any actual data access occurs, MM can't tell that there's an autoincrement column. More specifically, this if statement returns false:

The reason you're seeing this is because you are using untyped DataSets which are dynamically created the first time data is retrieved from the back end. I recommend calling the business object's GetEmptyDataSet() before adding your first new row.
