[xwiki-devs] org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction

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-upd...
