[castor-dev] Problem with updating object

[jonas_boner]

Hello.

I am trying to update an object, but it does not seem to work.
I have tried both short tx and long tx.

Here is the code I am trying to execute:

          db.begin();

                // Get the email
            Email email = (Email) db.load(Email.class,
                        new Long(emailId), Database.ReadOnly);
            db.commit();

            db.begin();

                // Update the field
            email.setIsDeleted(true);
            db.update(email);

            db.commit();
            db.close();

The email object has implemented the TimeStampable interface.
The error I am getting is:
        org.exolab.castor.jdo.ObjectModifiedException: Timestamp mismatched!

When I am running it in a short tx:

            db.setAutoStore(true);
            db.begin();
 
                // Getting the email
            Email email = (Email) db.load(Email.class, new Long(emailId), Database.ReadOnly);

                // Updating the field
            email.setIsDeleted(true);

            db.commit();
            db.close();
           
Then the error I am getting is:
            org.exolab.castor.jdo.ObjectModifiedException: Transaction aborted:
            Object of type foo.bar.Email with identity <id> has been modified by a concurrent transaction

Does anyone have an idea?
Please help.
Thanks in advance.
