LoadException when trying to load new window fxml - java-11

Question

I have javafx menu, I want to switch to another window. When I was using Java-8 everything worked, but now I switched to javafx-11 and java-11 and I cannot switch.
Switching code
AnchorPane pane = FXMLLoader.load(getClass().getResource("/main/main.fxml"), resources);
I was searching internet and stackoverflow and I tried following
1. In Inteliij idea I added all modules and libraries and applied the changes in Project Structure.
2. I added to src package module-info.java
3. I checked if fxml I am trying to load doesn´t contain any errors or unsed ids.
4. I checked names of controllers and fxmls I am trying to load
Code of the module-info.java
module duno {
requires javafx.fxml;
requires javafx.controls;
requires java.logging;
requires javafx.web;
opens main;
}
Code of the method from Controller which I am calling to get the Settings window
#FXML
void goto_settings(ActionEvent event) {
try {
ResourceBundle resources;
switch(settings.getLanguage().get(settings.getSelectedLanguage())) {
case "Czech":
resources = ResourceBundle.getBundle("/bundles/LangBundle_cz");
break;
default:
resources = ResourceBundle.getBundle("/bundles/LangBundle_en");
}
AnchorPane pane = load(getClass().getResource("/settings/settings.fxml"), resources);
rootpane.getChildren().setAll(pane);
} catch (IOException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
}

Don´t mind the English in the output it´s just the language used in app

Answer 1

I figured it out on my own.
Here is how I proceeded.
I read the error several times, and then I though it need to export something. So I found that module info have exports something to something. So I added exports settings to javafx.fxml.
Another problem that I could not access settings because rootpane was private and settings were not opened. So I tried open settings; and it works :)
So here is final version
module duno {
requires javafx.fxml;
requires javafx.controls;
requires java.logging;
requires javafx.web;
exports settings to javafx.fxml;
opens main;
opens settings;
}
I hope it helps someone in future with same error
