automapping

I am trying to map my collections with FNHib automapping. The problems that I want to solve are: 1) I want all my collections in the project to be mapped via private field. How can I say that globally? 2) Is there any way to automap bidirectional relationship without explicitly overriding each of my entities. class OrganizationEntity example: private ISet<> _collectionWarehouse; public virtual IEnumerable<WarehouseEntity> CollectionWarehouse { get{return _collectionWarehouse; } set{_collectionWarehouse = new HashedSet<WarehouseEntity>((ICollection<WarehouseEntity>)value)} } Class

i have the following scenario public abstract class BaseClass { public virtual int Id {get; set}; public virtual string Name {get; set;} } public class FirstSubClass : BaseClass { //properties and behaviour here } public class SecondSubClass : BaseClass { //properties of SecondSubclass Here } public class ProcessStep { public virtual IList<BaseClass> ContentElements {get; set;} } for mapping i have used following code snippet :- this._sessionFactory = Fluently.Configure().Database(SQLiteConfiguration.Standard .ConnectionString(@"Data Source=SqliteTestSqlDataAccess.s3db; Version=3; New=True;

I get this error: Unable to cast object of type 'NHibernate.Collection.Generic.PersistentGenericSet 1[IocWinFormTestEntities.People]' to type 'System.Collections.Generic.ISet 1[IocWinFormTestEntities.People]'. The entity: public class Event { public Event() { this.People = new HashSet<People>(); } public virtual Guid Id { get; private set; } public virtual ISet<People> People { get; set; } } Map override class: public class EventMapOverride : IAutoMappingOverride<Event> { public void Override(AutoMapping<Event> mapping) { mapping.HasMany(c => c.People) .AsSet() .Cascade.AllDeleteOrphan(); } }

Could some one help, how would I instruct automap to have not-null for a column? public class Paper : Entity { public Paper() { } [DomainSignature] [NotNull, NotEmpty] public virtual string ReferenceNumber { get; set; } [NotNull] public virtual Int32 SessionWeek { get; set; } } But I am getting the following: <column name="SessionWeek"/> I know it can be done using fluent-map. but i would like to know it in auto-mapping way. Thank you. Also, for reference properties ReferenceConvention need to be done. This is the code that works: public class ColumnNullConvention : IPropertyConvention {

Getting this everytime I attempt to CREATE a particular entity ... just want to know how I should go about figuring out the cause. I'm using Fluent NHibernate automapping so perhaps I haven't set a convention appropriately and/or need to override somethings in one or more mapping files. I've gone thru a number of posts on the web regarding this problem and having a hard time figuring out exactly why it is happening in my case. The object I'm saving is pretty simple. It is a "Person" object that references a "Company" entity and has a collection of "Address" entities. UPDATES work fine on
