The logic from the FieldMolder.getValue() method is correct. What does not
seem to be correct is your receipt of a TransactionNotInProgressException.
This exception is only thrown from within the DatabaseImpl. Please post
the relevant portion of your client code so that I can see the sequence
of events that is causing this to occur.
