Combo Box defining what appears in a Jlist

Hi!

When my combobox changes object, the Jlist that is set to change depending on which object is selected, doesn't change but instead just freezes the Jlist.

Edit: only the default selected object has it's DefaultListModel do what it's supposed.

here's the code

Code:

---

final JComboBox cb = new JComboBox(Personlista.Personlista);
   
    Person selected = (Person)cb.getSelectedItem();
    LanlistModel = selected.getList();
    lanlist = new JList(LanlistModel);

---

Code:

---

  cb.addItemListener(new ItemListener(){

                @Override
                public void itemStateChanged(ItemEvent e) {
                        Person selected = (Person)cb.getSelectedItem();
                LanlistModel = selected.getList();
                }
                        });

---

Code:

---

        public void setList(DefaultListModel list) {
                this.list = list;
        }

        public DefaultListModel getList() {
                return list;
