        Key: HB-426
    Summary: Enable observation of StaleObjectStateException
       Type: New Feature

     Status: Unassigned
   Priority: Major

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.1 beta 4

Description:
Please enable application software to take action whenever optimistic concurrency control fails (for example, whenever a database change fails because the version of an affected row is different from the version last read).  As I understand it, whenever Hibernate detects this it throws a StaleObjectStateException, which is helpful.  But StaleObjectStateException might propagate from any one of many Hibernate methods, which makes it difficult for an application to observe it.

I'd like one method in my application to be called whenever Hibernate throws a StaleObjectStateException.  (In my application, that method will evict stale entries from the global cache, using an algorithm that's too expensive to execute more frequently.)

The Observer pattern (from 'Design Patterns') seems applicable here.
