title: Have multiple FXML files (created in SceneBuilder), but only one controller. Does each scene load it's own copy of the controller?
body: <p>I have multiple FXML files I have created in SceneBuilder and one controller file.  When I edit a value (say for instance, an integer value) in one scene, and then switch scenes, that value does not seem to have been changed in the new scene.  </p>
  
  <p>When loading the fxml file for a scene, is my program loading a copy of the controller file just for (and used only by) that fxml file?</p>
  
  <p>Really appreciate any help you guys can give answering this question.</p>
