Error: Operation is not valid due to the current state of the object.

The Code:

    private ServiceOperationResult<EntityCollection<SurveyAnswerEntity>> UpdateSurveyAnswerRecords(EntityCollection<SurveyAnswerEntity> p_entities, bool p_isImported)
    {
        try
        {
            ServiceOperationResult<EntityCollection<SurveyAnswerEntity>> returnValue;

            foreach (SurveyAnswerEntity entity in p_entities)
            {
                entity.IsImportedCsv = p_isImported;
                entity.ImportDate = DateTime.Today;
            }

            returnValue = _persistence.SaveEntityCollection(p_entities);

            return returnValue;
        }

        catch (Exception ex)
        {
            if (_logger.IsErrorEnabled)
            { _logger.Error("Unexpected error in: UpdateSurveyAnswerRecord", ex); }

            return new ServiceOperationResult<EntityCollection<SurveyAnswerEntity>>(ServiceOperationResultType.OperationCallFailed, ex.Message + "\r\n" + "Method: UpdateSurveyAnswerRecord", null);
        }
    }

I've even tried manually setting IsDirty to true but that doesn't work either.

Please can you supply us with some more information to allow us to investigate further.

Thanks

So the exception is occuring on the call to SaveEntityCollection ? Could you also supply the exception details ?

Are any of the LLBLGen objects being Mocked ?

Thanks

Matt

Error: Operation is not valid due to the current state of the object.

I am mocking the _persistence object.

When I build the collection that I'm modifying and trying to save, I sort it. So the entities are not in the same order as they are in the database.

Library Version 2.5.0.0

That's not a valid runtime library version, please go back to the guidelines thread, to know how to get the RTL version.

I am mocking the _persistence object.

Is this a DataAccessAdapter object?

Sorry...the version is 2.5.8.604

_persistence isn't a DataAccessAdapter object, but we do utilize the DataAccessAdapter

Here is the code from _persistence:

    public ServiceOperationResult<T> SaveEntityCollection<T>(T p_EntityCollection) where T : IEntityCollection2
    {
        try
        {
            using (IDataAccessAdapter daa = GetDataAccessAdapter())
            {
                daa.SaveEntityCollection(p_EntityCollection);

                return new ServiceOperationResult<T>(ServiceOperationResultType.OperationCallSuccessful, p_EntityCollection);
            }
        }

        catch (Exception ex)
        {
            return new ServiceOperationResult<T>(ServiceOperationResultType.OperationCallFailed, ex.Message, p_EntityCollection);
        }
    }

On which line of code has the exception been thrown?

returnValue = _persistence.SaveEntityCollection(p_entities);

We still need to see the exception details - it appears from the stack trace you posted earlier that the error does not appear to be coming from LLBLGen.

Do you get the same error if you replace the mocked _persistence object with an actual one that does the same...?

Thanks
