I am trying to make an aplication that persists the folowing objects:
Department; Professor; UniversityClass; Student. The relations between are given by the folowing image:



The problem apears when I want to remove a UniversityClass from one Department. In this model the UniversityClass can not exist if it is not in a department. When I remove a UniversityClass from the Department colection I want it to be deleted from DB as well. To achive this I am using: cascade="all-delete-orphan" but it is not working. I am receiving the folowing exception: "You may not dereference an collection with cascade="all-delete-orphan""

NHibernate version: 1.0.

I think your problem is because you have the ClassesUntyped set mapped as inverse="true". I'm definitely not an expert on exactly how the inverse flag works, but If you want cascades to work correctly for a collection, you need to set inverse="false".

I think where you would want the inverse flag is if you had a bi-directional collection of director's in your UniversityClasses object, because I think the inverse flag indicates that you are not updating the collection from this end of the relationship.

stuow,

No, in fact using inverse="true" + cascade="all" or "all-delete-orphan" is the recommended implmentation of a parent-child relationship, which is what is what komiscaros is attempting to do. The inverse flag indicates that the relationship is managed via the UniversityClass.Department many-to-one. The cascade implies that actions taken on the parent will, well, cascade to the children.

Now, I'm not sure what is causing the error, since I can't see where a (or which) collection has been dereferenced. However, it does seem that this code:



is redundant, since this should be taken care of by the cascade in question. Does removing these lines have any effect?

Thank you for your posts,



I also expected that cascade will take care of removing the child record from DB for me but it does not.

If I coment out both:

then I receive the same exception.

If I coment out only the last line

then I receive the folowing exception: "not-null property references a null or transient value: nhRegistration.BusinessObjects.UniversityClass.Departmen"
I think this comes because I have a not-null constraint in DB for UniversityClass.deptid column.

I have read more carefull the log file. It appears that the problem comes from the fact that I use BindingList<> colection wrapped over NHibernate colections so the session's cached colections are unreferenced which it appears that can not be done for cascade="all-delete-orphan" colections.

I will try to use the NHibernate colections but in this case I will loose the easy binding to GUI.

You don't need to lose anything. Keep your wrapper collection for binding, just don't try to update back to NHibernate using the wrapped collection. I recommend exposing the underlying NHibernate collection from your wrapped collection and update using that collection.

The problem is that in my current implementation I do not keep any reference to NHibernate's colection.
For example:

I have chosen this approach because NHibernate "gives" me an untyped collection. I realize that it takes more time at loading, but it helps me in implementing the business rules and GUI.
May be I did not understand well your suggestion, but having this I do not see haw to apply it.
