Hi,
I have a model where an entity A has a recursive relationship as
parent "toParentOfTypeA()" and children "toChildrenOfTypeA()".
Consider it as a tree structured entity.
In the model have setup the entity to delete cascade.
In the entity I have overriden the method willDelete(). Now when I
delete the parent, it fires the willDelete() of it but does not
fire willDelete() of it's children. When I checked in the
willDelete() I found the toChildren() relationship is empty but the
children are there and I access it in the component when I generate
tree.
I just wanted to add that if you are calling something like setParent
instead of addObjectToBothSides that you will only be setting the
relationship one way. So from your children, you will be able to see
the toParent, but you will not see any children from the Parent's
toChildren. There's a property to do this automatically in Wonder,
but I think you need to be using wonder eogen templates for that
property to work.
If that isn't the case, then you may be crossing editing contexts.

Below is the source code.
Follwing method is overridden inside entity A.
public void willDelete() {
ERXUtilities.deleteObjects(editingContext(), toChildrenOfTypeA());
}
// below code is somewhere else.
A a = // object retrieved from the db.
a.delete();
Any Idea? If needed, I can send the source code too.
