I have just discovered a pattern.
On the second execution of the read, it is only the objects immediately
related to the User object that are loaded. The objects related to those
loaded objects are the ones that are not loaded. Has anyone seen a similar
problem?,
Glenn.

Subject: [castor-dev] Object Reloading Error
Hey,
I have a problem where two identical reads are producing different results
and anonmalous behaviour: -
m_db = m_jdo.getDatabase(); // Get the database
log( "Got handle to database" );
String _oql = "SELECT p FROM
com.spirentsystems.applications.aura.modules.enterprise.domain.User p";
m_db.begin(); // Start a new
transaction
m_query = m_db.getOQLQuery( _oql );
m_results = m_query.execute();
boolean entered = false;
while( m_results.hasMoreElements() ) {
User user = ( User ) m_results.next();
log( "User Id: " + user.getUserId() );
}
m_db.commit();
m_db.close();
The first time this executes, everything is correct, but the second time I
execute the above in the same session, practically none of the relationships
are loaded. But, if I do a commit the second time, Castor complains with: -
org.exolab.castor.jdo.PersistenceException: Object,
com.spirentsystems.applications.aura.modules.enterprise.domain.Division/1300
00000000000000000000000000, isn't loaded in the persistence storage!

Incidentally, the error above refers to an object that isn't loaded as it
should be with the above query, so it seems Castor expects it to be there.
