Name and version of the database you are using:Oracle 8

The generated SQL (show_sql=true):

According to Hibernate 3.02 doc chapter 10.11 'Transitive Persistence' it is possible to casacade the creation operation on associations. I did add a cascade="create,save-update" on all associations i used to achieve this. however, Hibernates throws a Exception telling the 'create' cascade is not supported. any idea why?

Mapping used:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="be.rmi.intranet.db.users" default-lazy="true">
 <class name="be.rmi.intranet.db.users.FunctionBackup" table="USER_FCT_BACKUP" lazy="true">
  <id name="id">
   <column name="backup_id" not-null="true" unique="true" sql-type="NUMBER"/>
      <generator class="sequence">
       <param name="sequence">user_function_backup_seq</param>
      </generator>
  </id>
   <property name="priority" column="PRIORITY" not-null="false"/>
   <many-to-one name="function" column="fct_id" not-null="true" cascade="create,save-update"/>
   <many-to-one name="user" column="empl_id" not-null="true"/>
 </class>
</hibernate-mapping>
