title: Replacing objects in ListView - JavaFX
body: <p>When I'm adding File type objects to a ListView, they are replaced.
  I don't know how to handle with that.</p>
  
  <p>Methods that operates on the ListView are: <code>save()</code> and <code>cellFactory()</code>.</p>
  
  <p><a href="https://pastebin.com/dXqQVd6r" rel="nofollow noreferrer">Here is code.</a></p>
  
  <pre><code>@FXML
  private Button folderButton;
  @FXML
  private TextField fileDirectory;
  @FXML
  private TextField fileName;
  @FXML
  private Button saveButton;
  </code></pre>
