thank first,
PersistenceBroker *delete elements* from the database that have been removed
from the collection only if i do this :
for example : A 1:n B
1. i get A from database using OJB Broker.
2. i delete one element B from A : A.getBCollection().remove(o);
in this case yes the PB delete the element from database . but in generale
we don't
invoke remove but we construct a new collection and we set it :
1. get A from database.
2. Collection bCol = new ArrayList();
A.setBCollection(bCol);
in this case the element that not figure in bCol are not deleted because i
use ArrayList. (in my Application i can't put RemovalAwareList directly
inorder to keep the application independent of OJB classes ...)
so what is the solution please ... without using ODMG ?????
Thanks
