FXMLLoader getController returns NULL?

by

Change this

@FXML
   public void editPerson() {
      try {
         FXMLLoader loader = new FXMLLoader(getClass().getResource(
               "PersonEditor.fxml"));
         PersonEditorCtrl ctrl = loader.getController();
         ctrl.init(table.getSelectionModel().getSelectedItem());
         Parent root = (Parent) loader.load();
         Scene newScene = new Scene(root);
         Stage newStage = new Stage();
         newStage.setScene(newScene);
         newStage.show();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }

To that:

@FXML
   public void editPerson() {
      try {
         FXMLLoader loader = new FXMLLoader(getClass().getResource(
               "PersonEditor.fxml"));
         Parent root = (Parent) loader.load();
         PersonEditorCtrl ctrl = loader.getController();
         ctrl.init(table.getSelectionModel().getSelectedItem());

         Scene newScene = new Scene(root);
         Stage newStage = new Stage();
         newStage.setScene(newScene);
         newStage.show();
      } catch (Exception e) {
         e.printStackTrace();
      }
   }

You first have to run loader.load() then you can get the Controller.
