    How to refresh an Entity instance after persisting its collection?

    Tong Wang Newbie

      I have two entity classes with a bi-directional one-to-many relation between them. Code below:

      public class Business extends EntityBase {
           @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "business")
           private List<Campaign> campaigns = new ArrayList<Campaign>(0);
      public class Campaign extends EntityBase {
           @ManyToOne(fetch = FetchType.LAZY)
           @JoinColumn(name = "BUSINESS_ID")
           private Business business;

      Then, by extending EntityHome, I have CampaignHome:

      public class CampaignHome extends EntityHome<Campaign> {
           private static final long serialVersionUID = -7083267087708513892L;
           @In(required=true) @Out
           private Business business;
           public void wire() {
           public String persist() {
                return "persisted";

      What I want to achieve is that after persisting a new Campaign, refresh the Business instance so that its campaigns collection will have the newly persisted campaign. Suggestions/help will be highly appreciated.
