As an administrator, when i tried to modify the access right of a particular user and then when i click on save, it gives me an exception saying org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction(or unsaved-value mapping was incorrect). What does this mean and how do i get rid of this problem..... -- View this message in context: http://www.nabble.com/org.hibernate.StaleObjectStateException%3A-Row-was-up… Sent from the XWiki- Dev mailing list archive at Nabble.com.
