Query not synchronized

Question

Hi,
I'm having some trouble on rendering a list where some of the row attributes have changed.
The list page renders a table where the value attribute is binded to a java.util.List in a request scope backing bean. I select one of the items and send it to the edition view, and change one or two attribute, call the service and merge the changes with the javax.persistence.EntityManager. Once finished I'm sent back to the list where I started. The one or two attributes happen to be in the columns the table is rendering, but they haven't changed. I check at the database and they do have changed, and if I go to other list where these change will cause this row not to be included it works fine, but when I'm back to the list the attributed remain unchanged.
I've checked and every time I go to the list, before and after the edition, the query to load the list is called. The java.util.List object is called from the backing bean, which is request scope. The query is created in the facade as follows:
public List<Result> getResults(String id, Long state) {
StringBuilder sql = new StringBuilder("select x.field_one, x.field_two, y.field_three from table_x x, table_y y where x.field_one = ?1");
if(null != state) {
sql.append(" and x.field_two = ?2");
Query query = em.createNativeQuery(sql.toString, Result.class);
query.setParameter(1, id);
if(null != state) {
query.setParameter(2, state);
return query.getResultList();
And the Result class is an entity without any real table attached to it.
@Entity
public class Result implements serializable {
//attributes + getters and setters
Any ideas why would this happen?
Thnaks in advance.

Try to add the following line before the invocation of query.getResultList():
query.setHint(TopLinkQueryHints.REFRESH, HintValues.TRUE);Add the following to your import statements:
import oracle.toplink.essentials.config.HintValues;
import oracle.toplink.essentials.config.TopLinkQueryHints;pino
