Hello,

My question is rather abstract but I was wondering why developer should manually remove given object from the associated objects' single- or many-valued properties prior delete?

I would like to automate the deletion by crawling all the associated object's collection and remove the current object from there. Have you guys done something like this so you can share opinions/patterns?

Thank you in advance!

Do you mean cascade delete?

I use hibernate annotation
@ManyToOne(cascade=CascadeType.REMOVE)
@OneToMany too

Not really, because CascadeType.REMOVE deletes the associated objects. I actually need to break the the relation to the associated objects and delete current object. I would like to avoid manually removing the object from associated object's collections.

Currently I get ConstarantViolationException if I don't break the relation prior delete.
