I am trying to insert or update an entity to the database using the EntityHome object, but it's not working.

@Name("personHome")
@Scope(ScopeType.CONVERSATION)
public class PersonHome extends EntityHome<Person> {

     @In(create = true)
     DelegationHome delegationHome;

     @Override
     @End
     public String update() {
          
          // New leader
          PersonHome leaderHome = new PersonHome();
          leaderHome.setId(delegationLeaderKey);
          Person leader = leaderHome.getInstance();
          
          // Add leader and current person entity to a new delegation record
          Delegation delegation =     delegationHome.createInstance();
          delegation.setLeader(leader);
          delegation.setDelegate(getInstance());
          
          getInstance().getDelegationsForDelegate().add(delegation);
//          delegationHome.persist();

          return super.update();
     }
}

When I call personHome.update() the records do not get updated in the database even when I call persist. What am I doing wrong here?
