How to update a @OneToOne relation?

Hi,
I have the following probleme:
I have an entity "Contact" which have two @OneToOne relations to an entity "Address". If I perform an update on the contact entity only the "simple properties" of type "String, Integer, Boolean, and so on) will be updated. The properties with an relation (@OneToOne for example) are not updated on transaction.commit() and manager.close(). The Update is only visible if I restart my application. Here the related code:

Code:

@javax.persistence.Entity
public class Contact {
   // ...
   private String firstName;
   
   @OneToOne(cascade = CascadeType.ALL, optional = true, fetch = FetchType.LAZY)
   private Address privateAddress;

   @OneToOne(cascade = CascadeType.ALL, optional = true, fetch = FetchType.LAZY)
   private Address commercialAddress;
   // ...

The update looks like this:

Code:

final Contact contact = ...
final EntityManager manager = factory.createEntityManager();

contact.setFirstName("NEW FIRST NAME"); // updated after commit
contact.getPrivateAddress().setStreet("NEW_STREET"); // not updated after commit

manager.getTransaction().begin();
manager.getTransaction().commit();
manager.close();

Does someone knows an solution?

Thanks :)

Best regards

Hi,
A update:
The address is updated in the database. I found the root causes of my issue. The @EntityListeners(...) of the contact entity will not be informed if a related entity has been changed (only if a own property has been changed). Is there a acceptable (automatic) way to in form the @EntityListeners of the contact entity if one related entity (address for example) has been changed?

/edit
My current (quite bad) solution is do disable the entity listener and to notifiy the entity listener manually. Is there a better way?

Thanks & best regards
