i am getting an exception and don't understand what causes it. It's an FX App with FXML files. At the init() part of the App i add a listener to a textfield which calls a function that monitors the String with a regex for a pattern. tf.textProperty().addListener( (observable, oldValue, newValue) -> { handleInput(newValue); }); the function: private void handleInput(String s) { s = s.toUpperCase(); Matcher matcher = Pattern .compile( "^[A-Z]{2}(20|21|22|23|[0-1]\\d)[0-5]\\d(20|21|22|23|[0-1]\\d)[0-5]\\d(T\\s|C\\s|TC|CT|\\s\\s)$") .matcher(s); if (matcher.find()) { // do something // then clear

Can anyone please suggest some links for using UITextField in cocos2d. I want to press on label, then the UITextField should get selected and I need to edit on that UITextField .
