          You can have two Seam components (thus two entity homes in your case) by using @Role annotation.
          Better solution I think is to have different DB structure :


          Menu:



          • id

          • code

          • (@OneToMany @JoinTable(name="MENU_LABELS")) List<Label> labels



          Label:



          • labelId

          • languageCode

          • value



          With this, you need only one entity home.

            There are several options.


            1. In Menu entity constructor you can populate labels attribute :


            public Menu() {
                labels = new ArrayList<Label>(2);
                labels.add(new Label("en"));
                labels.add(new Label("cn"));
            }



            2. Better solution in my opinion is to call custom method on MenuHome just before you start creating Menu, i.e. I do this from s:link :


            public void startCreateProcess() {
                getInstance().labels = new ArrayList<Label>(2);
                instance.labels.add(new Label("en"));
                instance.labels.add(new Label("cn"));
            }



            <s:link value="Create" view="/menu.xhtml" action="#{menuHome.startCreateProcess}"/>
