hibernate: l’identifiant généré par la séquence est différent de celui retourné par une select!

Bonjour,

En traçant les requêtes générées par hibernate lors de d’un merge, on s’est rendu compte que lors de l’insertion dans la table, l’identifiant généré par la séquence et qui est passé en paramètre de la requête est différent de celui retourné si on fait une select sur la même table.
En résumé l’identifiant retourné via une select est incrémenté de 1 par rapport a celui inséré lors du merge , on arrive pas à expliquer ce comportement et on sait pas si c’est du a une mauvaise configuration ou un défaillance de Oracle10g.
Pour plus de précision on utilise hibernate 3.2 et spring 2.5 :
Configuration :
[CODE<bean id="transactionProxy" abstract="true"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="transactionManager" />
</property>
<property name="transactionAttributes">
<props>
<prop key="insert*">PROPAGATION_REQUIRED</prop>
<prop key="update*">PROPAGATION_REQUIRED</prop>
<prop key="save*">PROPAGATION_REQUIRED</prop>
<prop key="*">PROPAGATION_REQUIRED, readOnly</prop>
</props>
</property>
</bean> [/CODE]
