Hi all,

Any idea why am I always getting originalValue as null?

I'm using LLBLGen Pro 5.10 and .NET8

using EduInspection.Data.EntityClasses;
using SD.LLBLGen.Pro.ORMSupportClasses;
using System.Collections;

namespace EduInspection.Core.Features.Auditing;

[DependencyInjectionInfo(typeof(SchoolGradeEntity), "AuditorToUse")]
[Serializable]
public class SchoolGradeAuditor() : AuditorBase
{
    private enum AuditType
    {
        DeleteOfEntity = 1,
        DirectDeleteOfEntities,
        DirectUpdateOfEntities,
        DereferenceOfRelatedEntity,
        ReferenceOfRelatedEntity,
        EntityFieldSet,
        InsertOfNewEntity,
        UpdateOfExistingEntity
    }

    private List<ActivityLogEntity> _auditInfoEntities = [];

    public override void AuditEntityFieldSet(IEntityCore entity, int fieldIndex, object originalValue)
    {
        var primaryKeyFieldsValues = entity.PrimaryKeyFieldInfos.Select(x => entity.GetCurrentFieldValue(x.FieldIndex));
        var logEntity = new ActivityLogEntity
        {
            EntityName = entity.LLBLGenProEntityName,
            FieldName = entity.Fields.GetFieldNames()[fieldIndex],
            OldValue = originalValue,
            NewValue = entity.GetCurrentFieldValue(fieldIndex).ToString(),
            ActionTypeIndex = (int)AuditType.EntityFieldSet,
            DateCreatedUtc = DateTime.UtcNow,
        };

        _auditInfoEntities.Add(logEntity);
    }
}

If you set an entity field of a new entity, the original value is null.

You have to provide more information regarding when it turns out to be null but you're sure it's not. (e.g. setting an entity field of an existing entity fetched from the db)

Yeah, that's it. Thank you!
