Does that help The new Dialog, if I am not wrong must be a new Stage ! Let us consider the new Stage to be modifyStage. We can call the onSetCloseRequest of the new Stage and put your code in it.
modifyStage.setOnCloseRequest(new EventHandler<WindowEvent>() {

    public void handle(WindowEvent paramT) {

like below fixes the issue I'm pulling a ResultSet from a MySQL database and attempting to dynamically build a TableView on a key down event. It works fine the first time I trigger it, but all subsequent times it creates duplicates of my initial columns while changing the row data for each column to match the new ResultSet. I want the TableView to be cleared completely every time this build function is run. , Just clear the current columns before you start adding them:

it helps some times When you add an item to an ObservableList, which is being displayed in a TableView, how can you update a row when a duplicate item is added? , Scan through the table's items to see if there is an existing item:
public void addItem(String itemName, int quantity, Double price) {

    Item entry = currentOrderTable.getItems().stream()
        .filter(item -> item.getItem().equals(itemName))
        .orElseGet(()-> {
             Item newItem = new Item(itemName, 0, 0);
             return newItem ;

    entry.setQuantity(entry.getQuantity() + quantity)
    entry.setPrice(entry.getPrice() + price);
