When I update xml schmas in budget.hbm.xml as your suggestion
> * <many-to-one name="oAirport" column="AirportID"*
> * class="Tec.Core.Model.Airport, Tec.Core" not-null="true"

I got the following exception class InvestmentCode.cs
------------------------------------------------------------------------------------------------------------------------
*public void AddBudget(Budget imntBudget){*
* if (imntBudget != null &&
!_lInvestmentCodeBudgets.Contains(imntBudget)){*
* imntBudget.oInvestmentCode = this;*
* _lInvestmentCodeBudgets.Add(imntBudget);
// System.NotSupportedException : Collection is read-only*
* }*
* }*
I do not know what going on here again.
Any suggestion?
Best regards,
Veasna
