Problem with static method for deleting

RichardETVS posted on Tuesday, March 20, 2007

Hi

I try the following code, in the BO class:

public static void DeleteEditableRoot(long Id)

        {

            Csla.DataPortal.Delete(Id);

        }

But I get an exception in MethodCalle.cs:

    public static MethodInfo FindMethod(Type objType, string method, Type[] types)

    {

      MethodInfo info = null;

      do

      {

        //find for a strongly typed match

        info = objType.GetMethod(method, oneLevelFlags, null, types, null);

The problem is that objType is null. Well, probably I am doing something wrong, but what?

Thanks for any help.

DataPortal.Delete() accepts a criteria object. The Criteria class must either be nested inside your business class, or it must inherit from CriteriaBase (which forces you to specify your business object type).
