title: What's the difference between fx:id and id: in JavaFX?
body: <p>Maybe a really newbie's question....</p>
  
  <p>I'm starting learning JavaFX in a FMXL Application using the Scene Builder, by reading this tutorials:</p>
  
  <p><a href="http://docs.oracle.com/javase/8/javafx/get-started-tutorial/fxml_tutorial.htm" rel="noreferrer">http://docs.oracle.com/javase/8/javafx/get-started-tutorial/fxml_tutorial.htm</a></p>
  
  <p>So once i applied some changes, an issue with this 2 IDs came up... I might have missed or confused something about them...</p>
  
  <p>Can anyone tell me in which cases they are used one or another?                   </p>
