I have an inheritance structure :

  1
 /  \
2   3

where:
 1 = Relation (SuperType) Abstract
 2 = Contact (SubType) Concrete
 3 = Organization (SubType) Concrete

I'm using a Generic Repository:

public class LlblGenRepository<TEntity> : IRepository<TEntity> where TEntity : EntityBase2, IEntity2
{
...
}

Now I want to save a ContactEntity and get the error: "The given key was not present in the dictionary"

I think this exception raises because there is no RelationEntity created before the ContactEntity is created. Even when I try to Create the RelationEntity earlier (adapter.SaveEntity((RelationEntity)ContactEntity) it still tries to create the ContactEntity instead of the RelationEntity.

So my question is: How can I create/store an entity with an abstract supertype?

If you want to instantiate/save entities they shouldn't be abstract. What kind of inheritance do you have? and Why do you want RelationEntity to be abstract in the first place?

I'm using a 'Target per entity' hierarchy.

The relation entity is general and contains fields which applies to both contacts and organizations. The relation enitty also contains the identifier, which is the pk-side for the fk in contact and organization.

Which runtime library version (build no.) are you using?

These are the libs i use:

SD.LLBLGen.Pro.ORMSupportClasses.NET20 - 3.1.11.527 SD.LLBLGen.Pro.LinqSupportClasses.NET35 - 3.1.11.518

The error i get wihle trying to save an concrete entity: "The given key was not present in the dictionary."

3.1.0.0 is not a correct build no.

Please follow the instructions here: http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=7722 Tot get the correct no. for both dlls.

These are the libs i use:

SD.LLBLGen.Pro.ORMSupportClasses.NET20 - 3.1.11.527 SD.LLBLGen.Pro.LinqSupportClasses.NET35 - 3.1.11.518

That's strange.

The base entity should be inserted automatically before the child entity is saved. So normally you don't need to cast or pre-save the base entity. Just save the entity in question, and the framework do the plumbing for you.

So I don't know why this is not working with you. Could you please provide a simple repro solution including the llblgen project file.

The strange thing is: I made a new project with the same hierarchy type and tried with a simple console app which worked fine.

Createing a console app in the project i'm working on, the error stays...

I've generated the code a couple of times which also doesn't help. It seems (in my opinion) the projectfile became "dirty".

I'll try to reproduce it...

Unfortunatly i can't reproduce it in another project.

I'm wondering which KeyValuePair is involved in the Save-action? What can i do more?

Mmmm :\ It might. Could you send us your .llblgenproj to examine it? You can open a HelpDesk thread (private) to attach your file.

I created a new ProjectFile for my project and now it works as expected.

I stripped the old-one. Where/how can i send you the old one?
