Hibernate version:3.1.2

Code between sessionFactory.openSession() and session.close():

log.debug("Testing update address...");
user.getAddress().setCountry(new Country("US"));
dao.saveObject(user);
log.debug("Country name is " + user.getAddress().getCountry().getCountryName());



I have two tables:
User (userId, name, addr1, addr2, city, state, countryCode)
Country (countryCode, countryName)

Address is a component class consisting of (addr1, addr2, city, state, country), where country is a class. User to Country is many-to-one. countryCode is the PK for country table.

Country constructor:
Country(final String countryCode) {
this.countryCode = countryCode;
}


The above code executes correctly. It changes the countryCode column of User table to "US". But when I call
user.getAddress().getCountry().getCountryName()
after the update, it returns null. It should hit DB and return the countryName.

If I retrieve the user by userId, then user.getAddress().getCountry().getCountryName() works correctly:
User user = (User) dao.getObject(User.class, new Long(1));
assertNotNull(user);
log.debug("Country name is " + user.getAddress().getCountry().getCountryName());

What is your mapping file look like?

Did you define a many-to-one relationship to the country entity or just defined a component class with properties. In the last case it won't probably work. It should need the relationship.

If I were you, rather than:

I'd use:


I don't know if it will work, but my experience with hibernate tells me to always (as far as possible) get objects from the database then to work with.
