null id Orchard repository creation Id identity on

Question

I use Orchard to create a new entry with this code

_repository.Create(new GMapZonePartRecord {
                Name = model.Name,
                Description = model.Description,
                Commune = model.Commune,
                Quarter = model.Quarter,
                Price = model.Price,
                StartZoom = model.StartZoom,
                StopZoom = model.StopZoom,
                Color = model.Color,
                GMapPartRecord = partRecord
            });

where _repository is IRepository. My code were working a long time ago and now I get an exception My column id is identity on and in migration.cs:

SchemaBuilder.CreateTable("GMapZonePartRecord",
            table => table
                .Column<int>("Id", col => col.PrimaryKey().Identity())
                .Column<string>("Name")
                .Column<string>("Description")
                .Column<string>("Color")
                .Column<int>("GMapPartRecord_Id"));

Here is the detail of error:

Thanks for any help, I really don't know where to search.

EDIT: After added source of Nhibernate 3.3.X, I found that the check that failed is not null value of ContentItemRecord. Any idea?

Answer 1

To debug I download NHibernate source from https://github.com/nhibernate/nhibernate-core/tree/3.3.x and discover that the null value were not id like the error message let us thinking but ContentItemRecord.

So I just add new value on this:

_repository.Create(new GMapZonePartRecord
            {
                Name = model.Name,
                Description = model.Description,
                Commune = model.Commune,
                Quarter = model.Quarter,
                Price = model.Price,
                StartZoom = model.StartZoom,
                StopZoom = model.StopZoom,
                Color = model.Color,
                GMapPartRecord = partRecord,
                ContentItemRecord = new ContentItemRecord()
            });

Now all is ok :)
