Eeek! Do you hear 30% data bloat? ;)

Thanks - I'll give this a try. I'm assuming that the following'll work:
Date newDateValue = rs.getDate(columnName);
ObjectAdapter restoredValue = IsisContext(). \
getPersistenceSession().\
getAdapterManager(). \
adapterFor(newDateValue);
((OneToOneAssociation) field).initAssociation(object, restoredValue)

Something to keep in mind.
Thanks,
