Hi,

i have a following methods:

protected void FetchEntity(IEntity2 entityToFetch)
        {
            using (DataAccessAdapterBase adapter = CreateAdapter())
            {
                adapter.FetchEntity(entityToFetch);
            }
        }


public void SaveLLBLGen(IEntityBase entity, bool refetchAfterSave = false)
        {
            using (DataAccessAdapterBase adapter = CreateAdapter())
            {
                adapter.SaveEntity((IEntity2)entity, refetchAfterSave, true);
            }
        }


public IContentMainContentEntity GetContentLLBLGen(long idMainContent)
        {
            MainContentEntity ret = new MainContentEntity(idMainContent);

            FetchEntity(ret);

            
            return ret;
        }

When I'll try to run the following test method:

var content = contentDao.GetContentLLBLGen(3807967);

contentDao.SaveLLBLGen(content);

The following error occurs:

The entity is out of sync with its data in the database. Refetch this entity before using this in-memory instance.

This is very strange - I've didn't modified an object at all. What could be wrong?

[Edit]

It seams, that I referenced to the db with old schema. It was weird, because an entity was correctly loaded, but it couldn't be saved even if I didn't changed anything.
