Hardy Ferentschik commented on HHH-4626:
----------------------------------------

Seems to me you are just missing the {{orphanRemoval=true}} option on your {{@OneToMany}} association.

> public Class Foo {
> @OneToMany(fetch=FetchType.LAZY, cascade={CascadeType.ALL}, mappedBy="foo")
> public List<Bar> getBars() {
>  return bars;
> }
> }
> // aFoo is persited
> Foo aFoo = ...
> aFoo.getBars().remove(0);  // remove the first
> aFoo.getBars().add(aBar);  // add new one
> em.merge(aFoo);
> For cascade={CascadeType.ALL}, it works for creating/deleting aFoo. 
> For merge, the new aBar is created, but the bar that was removed from collection are not deleted from persistence.
