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

My scenario is also similar...

When i try to save Product (with cascade save for ProductBasic), i get the following error:

org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of com.tietoenator.lis.db.impl.product.bo.CompProductBasicBO.useType
	at org.hibernate.property.BasicPropertyAccessor$BasicGetter.get(BasicPropertyAccessor.java:171)

I guess as i have used composite id and <generator class="foreign"> inside that, it treats it as component and when it tries to get a unique key for the instance using hashmap(), it throws exception..
I guess this is a bug in hibernate core...
I have checked this with Hibernate 3.2.6 and Hibernate 3.3.1 as well

> Hello, 
> This is the continuation of HB-389
> We develop an application which has very strong need for performance with several tens of million recordings. Partitioning is a need.
> So for that, I use <composite-id>. But my primary key is not a natural key, but a real technical key :
>  - column of partitioning for optimization of the data base 
>  - column of technical id
> So I need to have a generator, for exemple :
>     <composite-id name="id" class="IdPartition">
>         <key-property name="org" type="string" column="ORG"/>
>         <key-property name="id" type="long" column="ID"/>
>         <generator class="fr.test.xavier.IdPartitionGenerator">
>             <param name="table">TAB_SEQ</param>
>             <param name="column">LAST</param>
>         </generator>
>     </composite-id>
> The good news is that Hibernate can use that (HB-389).
> In fact, it is enough to modify the DTD to authorize <generator> in <composite-id> and it is all. The current code of Hibernate manages it very well. 
> Is it possible that Hibernate is enriched by this functionality?
