How does orphanRemoval work?
Why when I put it in a list does not work ex:
@OneToMany(mappedBy = "simulationMedia", cascade = CascadeType.ALL, orphanRemoval = true)
@JsonIgnore
private List<SimulationChemicalMedia> simulationChemicalMedias = new ArrayList<SimulationChemicalMedia>();
OrphanRemoval is present in most entity relationship annotations, and is used to define how a removal action assigned to an object will impact related objects.
OrphanRemoval marks "daughter" entities to be deleted when it has no other link to a parent entity, for example, when you have a car on a list of cars related to a dealership. If the concessionaire is excluded, if the car has no link with other concessionaires it will be deleted as well.
