Hi All,

I am working on a JSF/EJB3/Hibernate project. My issue is that I am trying to retrieve a persistent object but I need to change some of the fields before sending the object back to the UI. Again I do not want to persist the changes , they are temporary and only serve for displaying purposes. While doing that I get the following exception:

org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction.

From what I undstand this error is generated since the object is still connected to the persistent context. So I need to find a way to apply those changes without getting hibernate trying to persist them which results in the error I am getting.

Any replies are highly appreciated and please also let me know if I have misunderstood something about the framework.

Cheers.

For this purpose you must detach the object or set it to read-only:

detach:

Code:

session.evict(obj)            (or in future with JPA2: entityManager.detach(obj)  )

set read-only:
