I m using this gegnerator

public class StringIdGenerator implements IdentifierGenerator {
    final public static String NAME=StringIdGenerator.class.getSimpleName();
    public Serializable generate(SessionImplementor session, Object object) throws HibernateException {


        return  UUID.randomUUID().toString().replace("-","");
    }
}



@Entity
@GenericGenerator(name = "pt_sequence", strategy = "dao.StringIdGenerator")

public class P {
@Id

@GeneratedValue(strategy=GenerationType.IDENTITY,generator = "pt_sequence")
   String id; 
.......

Why after a insertion i see 2 element inserted , not one?

Hi, we are trying to reproduce the issue, could you add some more information? Which version of Hibernate OGM are you using? Which datastore? At the moment our tests seem to work. Thanks – Davide D'Alto May 31 '18 at 15:05
We might also need to see how you are inserting the entities – Davide D'Alto May 31 '18 at 15:09
By the way, is the problem occurring if you don't use the custom generator? – Davide D'Alto Jun 01 '18 at 14:15
I removed it and add id manually. In this way it works – abubi abubi Jun 01 '18 at 14:43
I'm glad that you have found a work-around. If you can still give us some more information or a small testcase to check the problem. We might be able to reproduce it and solve it. – Davide D'Alto Jun 04 '18 at 08:41
What are you trying to do should work and you shouldn't have to set the id manually (if you don't want to). – Davide D'Alto Jun 04 '18 at 08:42
