I have the following question about a one to one mapping.
As recommended by many Hibernate literature, I have one entity A that holds a reference to another entity B.
The life cycle of B is the same as the one for A.
So I have implemented the relation as a many-to-one with the flag inverse=true.
Now imagine that I load an instance of A from the database and replace the persistent version of B with a new one and update A. As expected, a new row is inserted into the table for B, the foreign key is updated in the corresponding row for A, but the old row used for the first instance of B is never deleted from the B table.

Any ideas or remarks ?
I used cascade="all" and don't have a reverse relation from B to A
