Retrive an Account using a long value and verify the generator is no longer used.

UpdateIdentifierDemo.java

// Fetch an account.  Notice that the id is now a long rather than an integer.
Account account = (Account)persistenceManager.findById(Account.class, 1l);
assert account.getAccountId() == 1l;

// This example creates a new account and attempts to save it without an identifier.
Account account2 = new Account();
persistenceManager.saveEntity(account2);

// The account ID was not auto incremented.
// This is because we removed the generator from the @Identifier annotation.
assert account2.getAccountId() == 0;
