Hi,

we now try using the DirectMode and get an exception during insert.
The error is ' ORA-01400: cannot insert NULL', but we did set a value.

Any Idea?

THX

Could you please specify the way you are creating and inserting the entity and, if possible, send us the exact model (or model with the related entity only) used for this? I've tried the following, and the insert was performed successfully:

Code: Select all

using (DataContext1 context = new DataContext1([connection string])) {

  context.PumaWorkflowExecutions.InsertOnSubmit(new PumaWorkflowExecution() {
    Id = 131928,
    WorkflowInstanceId = 4443644,
    StatusId = 1,
    Finished = 0,
    ModificationDate = DateTime.Now,
    WorkflowId = 0,
    RetryCount = 1,
    SophisUserId = 8402
  });

  context.SubmitChanges();
}

Also, did you try the latest 6.0.86 version of dotConnect for Oracle? Can the problem be reproduced with it?

The problem is reproducible on 6.10

The entity is filled in more than one function, but basically we are doing something like this:

Code: Select all

entity = new PumaWorkflowExecution();
entity.Id = NextSequenceNumber();
context.PumaWorkflowExecutions.InsertOnSubmit(entity);
FillDataObject(entity);
context.SubmitChanges();

The correct implementation is done on the methods

Code: Select all

class BaseClass
{
...
        public virtual T Save(Data.PumaDataContext context)
        {
            bool found = true;
            T entity = GetDataObjectById(context);
            if (entity == null)
            {
                if (Id == 0)
                    Id = GetNextSequenceNumber();
                entity = new T();
                (entity as IUniqueIdentified).Id = Id; // Must add the Id here to avoid error on the InsertOnSubmit
                found = false;
            }

            if (!found)
                GetStorage(context).InsertOnSubmit(entity);

            FillDataObject(context, entity);

            return entity;
        }

        protected virtual void FillDataObject(Data.PumaDataContext context, T entity)
        {
            entity.Id = this.Id;
        }
}

class WorkflowExecution: BaseClass
{
...
        protected override void FillDataObject(Data.PumaDataContext context, Data.WorkflowExecution entity)
        {
            if (WorkflowInstanceId == null && WorkflowId == null)
                throw new Exception("Either the workflow instance id or the workflow identifier must be filled");
            base.FillDataObject(context, entity);
            entity.WorkflowInstanceId = WorkflowInstanceId;
            entity.StateSequence = StateSequence;
            entity.TaskSequence = TaskSequence;
            entity.ActionSequence = ActionSequence;
            entity.Finished = Finished;
            entity.StatusId = (int)Status;
            entity.ProcessingServer = ProcessingServer;
            entity.ModificationDate = ModificationDate;
            entity.Comments = Comments.Truncate(4000);
            entity.PredecessorId = PredecessorId;
            entity.ParentId = ParentId;
            if (WorkflowId.HasValue)
                entity.WorkflowId = WorkflowId.Value;
            entity.ProductId = ProductId;
            entity.StatefulObjectId = StatefulObjectId;
            entity.RetryCount = RetryCount;
            entity.SophisUserId = SophisUserId;
            entity.ChildProductId = ChildProductId;
        }
...
}

I will send you a test project in a letter, please specify what should be changed in it to reproduce the issue. The DDL script for the table used in the sample is specified in the comments of program.cs.

We could reproduce the issue only in case that the RetryCount property of the entity class is either version or an auto-generated field.
