I have following entity classes:
Tectonic and Level have each a list of TectonicsLevels which references both of them. A fourth entity class TectonicsLevelLink references TectonicsLevel one time as parent and one time as child. TectonicsLevel in turn has two collections, a parent and a child collection of TectonicsLevelLink.
My question is (as I tried a lot of configurations without success): What is best practice removing a TectonicsLevel? In OnToMany relationships I have cascadeType.ALL set and orphanRemoval="true". I always get an OptimisticLockException when I remove a TectonicsLevel.
Maybe someone can give me a hint, at least where I find some usefull information about that?
