hi,

I want to save an object and it child cascade. but the child is not a new instance, how should i do it ?

E.G

class Item{
Set<Tag> tags = .... //cascade = "save-update".
...
}

class Tag{
Long id;
String tag; //this one is unique
....
}


everything is ok when save a new child. but when i replace with existing child (with already contain an id), i had exception.

all i want to do is save the existing child (Tag) when i call save().

how can i do it ?
