title: unable to add text to textarea
body: <p>I m looking forward to update a textarea based on some specific value.In order to make this task simpler I made this sample program that sets simple <code>client</code>   text in the text area but it is not visible in text area. Here is my code</p>
  
  <pre><code>public class myController extends Stage implements Initializable {
  
      @Override
      public void initialize(URL arg0, ResourceBundle arg1) {
           snames=new TextArea(); 
      }   
      public void serverStart(ActionEvent event) throws IOException, InterruptedException{
  
          Parent root = FXMLLoader.load(getClass().getResource("/application/serverSecond.fxml"));
          Scene scene = new Scene(root);
          scene.getStylesheets().add(getClass().getResource("/application/application.css").toExternalForm());
          this.setScene(scene);
          this.show();
          snames.setText("clients");
      }
      @FXML TextArea snames;
  }
  </code></pre>
  
  <p>I also tried removing this line <code>snames=new TextArea();</code> but then it shows <code>NULLPOINTEREXCEPTION</code> .Thanks for help </p>
