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

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
To be able to use <generator> with <composite-id>

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?
