One-to-many update error

What cause the following errors being thrown?
The following code is used, where prUpdate is of class PrBO and have one
to many relationship with PrItemBO class.
 
 
            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!
 
regards,
Stephen

Re: One-to-many update error

Posted by Thomas Mahler <th...@apache.org>.

Hi STephen,

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
