Failed to execute command "NHibernate.Collection.Generic.PersistentGenericSet`1 in System.Collections.Generic.IList`1

Question

I have a domain class:

public class Agencia : IEntity { public virtual int Id { get; set; } public virtual string Nome { get; set; } public virtual string Identificacao { get; set; } public virtual IList<Pessoa> Gerentes { get; protected set; } public Agencia() { Gerentes = new List<Pessoa>(); } public virtual void AddGerente(Pessoa gerente) { Gerentes.Add(gerente); } public virtual void AddGerentes(params Pessoa[] gerentes) { Parallel.ForEach(gerentes, (pessoa) => Gerentes.Add(pessoa)); } } public class Pessoa: IEntity { public virtual int Id { get; set; } public virtual string Nome { get; set; } } 

Using this convention (defined as set AsSet )

 public class AgenciaConvention : IAutoMappingOverride<Agencia> { public void Override(AutoMapping<Agencia> mapping) { mapping.HasManyToMany(a => a.Gerentes).Cascade.AllDeleteOrphan().AsSet().Not.Inverse(); } } 

When I run this test:

 [TestMethod] [Description("Uma agência tem vários gerêntes")] public void AgenciaTemVariosGerentes() { // Arrange var fix = new Fixture(); var currentUser = GetLoggedUser(); // Create a List<Pessoa> var gerentes = fix.Build<Pessoa>() .With(p => p.Nome) .With(p => p.CPF) .With(p => p.CreateBy, currentUser) .OmitAutoProperties() .CreateMany<Pessoa>(10).ToList(); // Action new PersistenceSpecification<Agencia>(Session) .CheckProperty(p => p.Nome, fix.Create<string>().Truncate(80)) .CheckProperty(p => p.Identificacao, fix.Create<string>().Truncate(10)) .CheckReference(p => p.Regional, fix.Build<Regional>() .With(p => p.Nome) .OmitAutoProperties() .Create() , new IDEqualityComparer()) .CheckList(p => p.Gerentes, gerentes, new IDEqualityComparer()) .CheckReference(p => p.CreateBy, currentUser, new IDEqualityComparer()) .VerifyTheMappings(); // Assert } 

How to check this list?

The collection must be AsSet , it is necessary that the "Parent and child" fields be PK, FK

Thanks.

Answer 1

Sets do not implement IList<T> .

Define your properties as ICollection<T> .
