JavaFX 2.0 FXML resource loading error - resources

Question

#Override public void start(Stage primaryStage) {
try {
stage = primaryStage;
gotoLogin();
primaryStage.show();
} catch (Exception ex) {
Logger.getLogger(App.class.getName()).log(Level.SEVERE, null, ex);
}
}
enter code here
public User getLoggedUser() {
return loggedUser;
}
public boolean userLogging(String userId, String password){
if (Authenticator.validate(userId, password)) {
loggedUser = User.of(userId);
gotoProfile();
return true;
} else {
return false;
}
}
public void userLogout(){
loggedUser = null;
gotoLogin();
}
private void gotoProfile() {
try {
replaceSceneContent("../skinFolder/fxml/profile.fxml");
} catch (Exception ex) {
Logger.getLogger(App.class.getName()).log(Level.SEVERE, null, ex);
}
}
private void gotoLogin() {
try {
replaceSceneContent("../skinFolder/fxml/login.fxml");
} catch (Exception ex) {
Logger.getLogger(App.class.getName()).log(Level.SEVERE, null, ex);
}
}
private Parent replaceSceneContent(String fxml) throws Exception {
Parent page = (Parent) FXMLLoader.load(App.class.getResource(fxml), null, new JavaFXBuilderFactory());
Scene scene = stage.getScene();
if (scene == null) {
scene = new Scene(page, 700, 450);
scene.getStylesheets().add(App.class.getResource("../skinFolder/css/defaultSkin.css").toExternalForm());
stage.setScene(scene);
} else {
stage.getScene().setRoot(page);
}
stage.sizeToScene();
return page;
}}
So i am trying to use the sample of the FXML Login example, only i give other way for the fxml. And in the fxml files i gave the way to the controller.
The log shows those errors:

#FXML private Label errorMessage;

if(!App.getInstance().userLogging(userId.getText(), password.getText())){
errorMessage.setText("Username/password combination is invalid.");
}
}
}
And the line 28 is:
if(!App.getInstance().userLogging(userId.getText(), password.getText())){
I mention that the fxml files are in another folder the Main file folder. I don't get why i get this error when i am using the example gave by the Oracle, but with another folder structure!
My app folder structure:
Main
Model
Security
skinFolder - css
skinFolder - fxml
skinFolder - controllers
Here is the profile.fxml code:

Anyone any ideas?

Answer 1

I think it is related to your previous question (JavaFX 2.0 load fxml files from subfolder fails). See this answer. Same here for processUpdate action.

Answer 2

There is a problem in your profile.fxml file. You didn't include error description in stacktrace but most probably you have wrong or misspelled attribute tag in there.
Please, add profile.fxml and full stack trace to the post if you need more help.
