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 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4046948#...
