Remarks
OptimisticLockException is thrown when an attempt is made to save an entity and it is detected that the database record has been modified since the time the entity being edited was retrieved from the database. This is a safety mechanism used to prevent one author from inadvertently overwriting the changes of another author. For individual entity updates, this is determined by comparing the last modified date of the entity to the last modified date of the database record. For bulk updates (and resource table entities) this is determined by comparing the original DataSet values with those currently in the database.
