title: Using JavaFX scene builder to fill fx id with buttons in an array
body: <p>I need 15 buttons in my application but I dont want to declare them one by one like</p>
  
  <pre><code>@FXML
  private Button button1;
  @FXML
  private Button button2;
  @FXML
  private Button button3;
  ...
  ...
  ...
  ...
  </code></pre>
  
  <p>Instead, I want to this, create a array of buttons.</p>
  
  <pre><code>@FXML
  private Button[][] button = new Button[5][3];
  </code></pre>
  
  <p>However, In the scene builder, there is only one button that I can choose and I think it reference to the array not the single button element.
  Is there any way that I can easily make this work?</p>
