Hi Everybody,

I have developped an Hibernate-based application that creates parent/ childs elements mapped against Mysql Database.
When I try to create a directory (ie : a parent with its childs).
I get the following exception :

Caused by: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.itic.appserver.business.item.ItemFolder#3157]
at org.hibernate.persister.entity.BasicEntityPersister.check(BasicEntityPersister.java:1441)
at org.hibernate.persister.entity.BasicEntityPersister.update(BasicEntityPersister.java:1986)
at org.hibernate.persister.entity.BasicEntityPersister.updateOrInsert(BasicEntityPersister.java:1909)
at org.hibernate.persister.entity.BasicEntityPersister.update(BasicEntityPersister.java:2149)
at org.hibernate.action.EntityUpdateAction.execute(EntityUpdateAction.java:75)

Though the parent is always created first and the creation of a child is synchronized (locked to allow single loading of the parent to create the child), the exception stills arises.

Thank you in advance for your help.
