Right...I've changed the code in the Dev Guide as you listed above. You need one additional step for the default values to work properly. I'm not sure if this step is your current version of the Dev Guide Jump Start, but you need to put the following code in the OrderDetail business object's Hook

/// <summary>
/// Set any default values specified in the Default Value object
/// </summary>
/// <param name="dataRow">DataRow being added</param>
protected override void HookSetDefaultValues(DataRow dataRow)
{
	if (this.DefaultValues != null)
	{
		OrderDetailDefaultValues Defaults = (OrderDetailDefaultValues)this.DefaultValues;
		dataRow["OrderID"] = Defaults.OrderID;
	}
}
