 *<B>Assertion Description: </B>
If the transaction in which an instance is made transactional (by
calling PersistenceManager.makeTransactional or makeTransactionalAll) is
rolled back, then the transient instance takes its values as of the beginning of the
transaction, if the call to makeTransactional was made prior to the beginning of the
current transaction.
