    copied!<p>I have one problem with my configuration of play framework, when I insert a new <code>Notification</code> I have received the error. I don´t know why this error occured. Because I extends <code>Model</code> class, Play must generated a new ID for each row.</p> <p>If you can say to me what is the problem, or other better way to do this, Maybe if I extends the <code>GenericModel</code> and I do the code that is commented like this:</p> <pre><code>// @Id // @GeneratedValue(strategy = GenerationType.AUTO) // public long id; </code></pre> <p>but if I do this, How I must do the insert a new row?</p> <p>Thanks a lot!!!!</p> <hr> <p>Error found:</p> <blockquote> <p><strong>PersistenceException occured</strong> : <code>org.hibernate.HibernateException</code>: The database returned no natively generated identity value</p> </blockquote> <p>This is <code>/app/controllers/WSConfiguracion.java</code> :</p> <pre><code>if (cliente.valorBateria &lt; filasConfiguracionClientes.get(i).limiteBateria) { if (!estadoNotificacion.hayNotiBateria) { // code below generated the error Notificacion notificacion = new Notificacion( filasConfiguracionClientes.get(i).imeiadmin,imei, "bateria baja" ).save(); estadoNotificacion.hayNotiBateria = true; //notificacion.save(); estadoNotificacion.save(); renderText("NOTIFICA BATERIA"); } } else { ... } </code></pre> <h3>This is my model.</h3> <pre><code>package models; import javax.persistence.Entity; import play.db.jpa.Model; @Entity public class Notificacion extends Model { //@Id //@GeneratedValue(strategy = GenerationType.AUTO) //public long id; //@Id public long imeiadmin; //@Id public long imeiclient; public String detalleNotificacion; public Notificacion(long imeiadmin, long imeiclient,String detalleNotificacion) { this.imeiadmin = imeiadmin; this.imeiclient = imeiclient; this.detalleNotificacion = detalleNotificacion; } } </code></pre>
