Hi,
we have this complex scenario:
public Class A{
private long id;
@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, orphanRemoval
= false)
private List<A> child = new ArrayList<A>();
@ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY, optional =
true)
private A parent;
}
On the client I have a tree showing our objects. I want to edit an item of
the tree and change its parent. So I make a request to server in which I
persist the item I changed. But in this manner on the server I have an
ConstrainViolationException because the old parent still have the object
the i changed on his list's child. So, in order to make work this example I
have to make 2 requests, the first to modify the old parent's child list,
and then a request to modify the item I changed. It's work fine but this
not guaratees the transaction.
Any suggestions?
Thanks
Daniele
