I have a Java Swing application using a JList to show some data from a DB.

I am using DefaulListModel as the data model for the list in this way:

void PopulateSoldiersList() 
{
      try
      {
           soldiersListModel = new DefaultListModel();
           for (Soldier i : myBackEnd.GetAllSoldiers())
           {
                 soldiersListModel.addElement(i);
           }
           this.listSoldiers.setModel(soldiersListModel);
      }
      catch (Exception ex) {// Error Message}
}

And for some reason, the list just stays empty...

I even did make sure at runtime that all the data is set up properly in the data model and even in the "dataModel" property of the JList!

In other place at the app i have a similar problem, but there, sometimes the list show few items from the model (but not all of them)

I have no idea where to go from here...

please help. Thanks!
