title: JavaFX Rotate ImageView
body: <p>I'm trying to rotate an <code>ImageView</code> 90 degrees (JavaFX) each time the button is clicked:</p>
  
  <pre><code>private void rotate90(ActionEvent e){
      if(currentImage != null){
          imageView.setRotate(90);    
      }
  }
  </code></pre>
  
  <p>but my code only rotates <code>ImageView</code> once, and after that it just stops.</p>
