Hi Tim,

yes, those are returning true (got bitten by that some months back).

The problem I am having is the DataSets of the child objects are empty during the save!

My code does this:

                oPolicyLoan = new PolicyLoan();
                oPolicyLoan.GetEmptyDataSet();
                oPolicyLoan.NewEntity();
                oPolicyLoan.Entity.PolicyHeaderFK = oPolicyHeader.Entity.PolicyHeaderPK;
                oPolicyLoan.Entity.LoanDate = DateTime.Now;
                oPolicyLoan.Entity.LoanAmount = (Decimal)oPolicy.Entity.Premium;
                oPolicyLoan.Entity.LoanType = "APL";
                oPolicyLoan.Entity.UserFK = userPK;

then this:

mmSaveDataResult result = this.oPolicyHeader.SaveEntity();

oPolicyLoan is registered as a child of oPolicyHeader.

At the point in time when the SaveEntity is called, oPolicyLoan.DataSet has the data that I expect in it. As soon as I step into the SaveEntity code, oPolicyLoan.DataSet becomes disabled in the Watch window. Does that mean it is going out of scope? The parent is saving OK.

>make sure if you are using Hook Pre save methods that you are returning true for the save to complete.
