I have a page that the user creates a customer, order, and orderlines at the same time.
(leaving out orderlines for clarity)

When I save (insert) a NEW parent object:

mmSaveDataResult result = this.Save( oCustomer );

child business object tables get saved, but foreign keys DO NOT get populated with the Parent foreign key value.

I traced through MM code, and it seems Parent foreign keys ONLY get saved in child objects if the value already exists before the save. (I could be wrong about this.)

Maybe I'm doing something wrong, please avise.

Thanks!

Business object settings follow:

Business.cs
public ABusinessObject()
{ ...
 this.RetrieveAutoIncrementPK = true;
 this.AutoSaveOnParentSaved = true;
}

public CustomerBusiness()
{
 this.TableName = "Customers";
 this.PrimaryKey = "CustomerID";
 this.ClearOnFillDataSet = true;
 this.AutoUseTransactions = true;
}
public OrderBusiness()
{
this.TableName = "Orders";
this.PrimaryKey = "OrderID";
this.ForeignParentKeyField = "CustomerID";
}

page

 // declare BusinessObjects
 ...
private void Page_Load(object sender, System.EventArgs e)
{
 // instantiate the business objects and register with the form
 ...
 // create business object hierarchy
 oCustomer.RegisterChildBizObj(oOrder);
 ...
 
 if (! IsPostBack)
 {
   if (Request.QueryString["id"] == String.Empty)
   {
     oCustomer.GetEmptyDataSet();
     oCustomer.NewRow();
     dsCustomer oCustomer.GetCurrentDataSet();

     oOrder.GetEmptyDataSet();
     oOrder.NewRow();
     dsOrder oOrder.GetCurrentDataSet();
   }
   else 
     // get data from db
   ...
 }
}
