This is a mapping error as indicated by the ERROR messages.
AFAIK PrItemBO does have a property prNo.
The (derived ?) class PrItemView does not have the respective getter/setter method?
Try to add these getter/setter on PrItemView.
You could also try to use a different PersistentField Implementation in OJB.properties.
cheers,
Thomas

db.open(site.getRepository(), Database.OPEN_READ_WRITE);
tx = odmg.newTransaction();
tx.begin();
tx.lock(prUpdate,tx.WRITE);
tx.commit();
Can someone please help??? Thanks in advance!
