Subject RE: How to debug object retrieveal in JPA?
Date Fri, 27 Apr 2007 02:14:49 GMT
I had suspected the Locale so I made a set/getLocale that communicate in String.
I figured that openJPA does not actually care how I implement.

But for this run I removed it completely and did a clean rebuild. Good news and
bad the exception changed: 


java.util.NoSuchElementException: The result list has been closed.

Now we're getting somewhere.... what happens if you remove the Locale field from
the Person class?
