----------------------------------

Please attach a runnable test case (Java + mapping) that reproduces the problem.

>                 Key: HHH-3151
>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3151
>             Project: Hibernate3
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 3.2.5
>         Environment: hibernate 3.2.5
>            Reporter: boris schukin

> Example: 
> Let's  we have one class "MetaMethod"  and  second class "MetaParameter" .
> Class MetaMethod has a list of MetaParameters.
> Corresponding tables are: 
> CREATE TABLE META_METHOD
>  (ID VARCHAR2(50) NOT NULL
>  ,CODE VARCHAR2(40) NOT NULL
>  ,BCN_CODE VARCHAR2(40) NOT NULL
>  ,NAME VARCHAR2(100)
>  )
> ALTER TABLE META_METHOD  ADD (CONSTRAINT SK_BFN_PK PRIMARY KEY   (ID))
> ALTER TABLE META_METHOD ADD (CONSTRAINT SK_BFN_UK1 UNIQUE   (CODE  ,BCN_CODE))
> CREATE TABLE META_PARAMETER
>  (ID VARCHAR2(50) NOT NULL
>  ,BFN_CODE VARCHAR2(40) NOT NULL
>  ,BCN_CODE VARCHAR2(40) NOT NULL
>  ,SEQUENCE_NUMBER NUMBER(4,0) NOT NULL
>  ,TYPE VARCHAR2(255) NOT NULL
>   )
> ALTER TABLE META_PARAMETER  ADD (CONSTRAINT SK_BFA_PK PRIMARY KEY   (ID))
> ALTER TABLE META_PARAMETER ADD (CONSTRAINT SK_BFA_UK1 UNIQUE    (BFN_CODE, BCN_CODE   ,SEQUENCE_NUMBER))
> ALTER TABLE META_PARAMETER ADD (CONSTRAINT SK_BFA_BFN_FK1 FOREIGN KEY   (BFN_CODE  ,BCN_CODE) REFERENCES  META_METHOD (CODE   ,BCN_CODE))
> You see, the foreign key (BFN_CODE  ,BCN_CODE) on the table META_PARAMETER  is organized by native key (CODE  ,BCN_CODE) of the META_METHOD table.
> Structure of classes is simple (in my opinion), so i introduce the hibernate mappings: 
> <class name="com.stinscoman.kernel.api.meta.MetaMethod"
>            table="META_METHOD" >
>         <id name="id" column="ID" length="40" type="long">
>             <generator class="assigned" />
>         </id>
>         <properties name="theKey" unique="true">
>             <property name="code" column="CODE" not-null="true"/>
>             <property name="bc" column="BCN_CODE" not-null="true" />
>         </properties>
>         <property name="name" column="NAME" />
>         <list name="parameters" cascade="all-delete-orphan">
>             <key  property-ref="theKey" not-null="true" update="false">
>                 <column name="BFN_CODE" not-null="true"/>
>                 <column name="BCN_CODE" not-null="true"/>
>             </key>
>             <list-index column="SEQUENCE_NUMBER" />
>             <one-to-many class="com.stinscoman.kernel.api.meta.MetaParameter"/>
>         </list>
>     </class>
>  <class name="com.stinscoman.kernel.api.meta.MetaParameter"
>            table="SK_BFN_ARGUMENT">
>         <id name="id" column="ID" length="40" type="long">
>             <generator class="assigned"/>
>         </id>        
>         
>     </class>
> Now, somewhere in hibernate session, i try to put a parameter to method  
> MetaMethod method = ... <the code to obtain MetaMethod object>
> MetaParameter param = ... <the code to obtain MetaParameter object>
> method.getParameters().add(  param  );
> Ok. When session is flushing i always have:
