hey guys,

I have this scenario:

Object A {
Set<Object B> bSet;
}
A and B is bidirectional one-to-many
Object B {
Object c;
setC(Object c) {}
}
B and C is unidirectional many-to-one
Object C {
String name;
}

I changed the property [name] value from 'tom' to 'jack' of object c and called the setter of setC(){} of object B; then, called A.getBSet().add(c), and save object A.
Here is problem, after invoking the save method for object A, I try to use AbstractPersistentCollection.getStoredSnapshot() to get the snapshot of bSet, and get object c to see what is the previous value and what is the new value, but I always get the saved value, I just can't get the previous value.
Any idea about this?

Thanks a lot.
