Hi I have an entity Client representing an actual table in the database, i want to specialize it into other subtypes like IndividualClient based on the Client.IsIndividual = true. IndividualClient is not a physical table Using Inheritance Type : Target Per Entity Hierarchy

Problem is the validate entity check requires IndividualClient entity to map to a physical table

What am i doing wrong

TargetPerEntityHierarchy does not require that subtypes should map to a physical table. TargetPerEntity does.

Could you change IsIdividual to another type (string, or int)?

Thanks it worked

Can i have more than on Discriminator field for a super type on the subtypes Say field isIndividual is used between Client and IndividaulClient and field Isguarantor is used for the subtype Guarantor which is also not mapped ?

Just one Discriminator field. Try to mergethem both in one field.

Where can i find this in the documentation or any examples you know online

What do you want to find. When I say merge them, I mean logical wise, use one field to discriminate between different types, there is absolutly no reason to have 2 discriminator fields.

ok got the principal applied with discriminate fields

Another issue am facing here How can i add another entity to a typed list i have created when i add the 1st entity there are no more selection of entities allowed. Based on the documentation adding more entities should be possible

Iam using NHibernate ORM

1. You create an entity: Project->New->Entity (Ctrl+Shift+E)
2. Right click on that new entity and click on "Make subtype of...", then you select the base entity. More info here.
