Any way to access original field values by name from Auditor context

[James Talbut]

Hi,

I'm trying to record old and new field values in an Auditor.
Using something like this I can get the new value (using the 
audited.getUpdatedFields() to provide the values for 'field'):

    private Object getFieldValue(Broker broker, Object object, String field) {
        if (object == null) {
            return null;
        }
        PersistenceCapable persistenceCapable = 
ImplHelper.toPersistenceCapable(object, 
JPAFacadeHelper.toEntityManager(broker));
        OpenJPAStateManager stateManager = 
(OpenJPAStateManager)persistenceCapable.pcGetStateManager();
        if (stateManager == null) {
            return null;
        }
        int fieldIdx = stateManager.getMetaData().getField(field).getIndex();
        Object value = stateManager.fetch(fieldIdx);
        if ((value instanceof RowSetHolder) &&
                (((RowSetHolder)value).getSize() == 0)) {
            return null;
        }
        return value;
    }

But the old value has no state manager, so pcGetStateManager always returns 
null.

The old object does have the correct values set on it, but I don't have to have 
to use reflection (and somehow work out the mapping from field name to method 
name).

Is there any equivalent to the above that will work for the old values (as 
returned by audited.getOriginalObject()) ?

Thanks.

Jim
