[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Unique entity classes mapped to same table

[asmithJBoss]

Greetings,

I have the following scenario:

* Two distinct entity classes (A and B) are mapped to the same table
* Each entity class is mapped to distinct columns, except for two: the primary key, and another field that is updated by the database itself when the submit occurs, are both in each entity class

I have one method that does a find() on an instance of class A and updates it, and another method that does a find() and update on class B.  

Within the same transaction context, I call the method that updates Class A with a given primary key, then I call the other method that updates Class B using the same primary key.

When there are updates to both entities I get a StaleObjectStateException - is there any way that I can update two entity classes mapped to the same row within the same transaction context?

I have tried a merge after updating the second bean, but that obviously doesn't work.

Thanks,

Andrew
