      java.lang.Exception
          java.lang.RuntimeException

All Implemented Interfaces:

java.io.Serializable, NonFatalException

public class OptimisticLockException
extends ManagedRuntimeException
implements NonFatalException

This Exception gets thrown by Business Facade operations when that operation detects that the requested modifications to the database are impossible because the information the User Interface is supplying is stale at this point. This is the case when some other user changed the relevant data after the current user retrieved it from the database. A typical reaction by the UI code is to inform the user that his modifications could not be performed and ask him to re-apply his changes.
