JAVAFX - unable to add items to listview

I have a Tab called chat. Inside this Tab I have a list of users as ListView<string>. The content of this ListView was loaded from FXML file using: 

FXMLLoader.load(getClass().getResource("chat.fxml"))

I am trying to add items to my listview using java, but when I open the GUI, chat tab, the items I add does not get displayed in the users listview.

One of the ways I tried was:

List<String> values = Arrays.asList("one", "two", "three");
listOfUsers.setItems(FXCollections.observableList(values));

I have tried other ways as well, but nothing seems to work. I'd appreciate your help.

thanks guys..
the problem was that my listView of users was created by the FXML loader, and then by mistake i initialized it again in the java code, so all was needed is deleting the row:

listOfUsers=new ListView<String>();

the file chat.fxml has fx:controller?!

You need... 

xmlns:fx="http://javafx.com/fxml" fx:controller="DIRECTORY.FILE" //FILE.java

Try this

BorderPane pane = null;
    try {
        pane = (BorderPane) FXMLLoader.load(HERENAMECLASS.class.getResource("chat.fxml"));
        pane.getStyleClass().add("main");
    } catch (IOException ex) {

        Logger.getLogger(HERENAMECLASS.class.getName()).log(Level.SEVERE, null, ex);
        System.exit(-1);
    }
