Alterar a scene de um stage a partir do controller?

Olá. Eu estou iniciando no JavaFX. Eu fiz um projeto onde eu necessito alterar a scene do meu stage a partir dos controllers.
Eu elaborei a seguinte estrutura:

package com.tkfentretenimento.meusdados.view;

import java.io.IOException;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;

public class Install extends Application{

	public static Stage stage;
	
	public static void main(String[] args) {
		launch(args);
	}
	
	public void start(Stage primaryStage) throws Exception {
		stage = primaryStage;
		Pane root = FXMLLoader.load(getClass().getResource("ServiceTerms.fxml"));
		primaryStage.setScene(new Scene(root,500,500));
		primaryStage.setTitle("Registrar-se");
		primaryStage.show();
	}
	
	public static void changeScene(int index) throws IOException{
		Pane root = null;
		switch(index){
		case 0:
			root = FXMLLoader.load(Install.class.getResource("ServiceTerms.fxml"));
		case 1:
			root = FXMLLoader.load(Install.class.getResource("DeviceName.fxml"));
		case 2:
			root = FXMLLoader.load(Install.class.getResource("EnableServices.fxml"));
		case 3:
			root = FXMLLoader.load(Install.class.getResource("CloudServiceSelect.fxml"));
		}
		stage.setScene(new Scene(root,500,500));
	}
	
}

Daí eu chamo o método changeScene a partir dos controllers e passo o index da scene. Porém está sendo gerada esta exceção somente quando eu troco da scene ServiceTerms (essa carrega sem problemas, e todas estão no mesmo pacote junto a classe install (as classes controllers estão em outro pacote)):

Olá

Poste o código desta classe DeviceName.java. O erro tána linha 22 dela.

T
Thallysson

Esta é a classe:

package com.tkfentretenimento.meusdados.controller;

import java.io.IOException;

import com.tkfentretenimento.meusdados.model.ConfigDAO;
import com.tkfentretenimento.meusdados.view.Install;

import javafx.application.Platform;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;

public class DeviceName {
	
	@FXML private Button prox;
	@FXML private TextField name;
	
	public void initialize(){
		prox.disableProperty().bind(name.textProperty().isNull());
	}

	@FXML public void next() throws IOException{
		ConfigDAO.setDeviceName(name.getText());
		Install.changeScene(2);
	}
	
	@FXML public void back() throws IOException{
		Install.changeScene(0);
	}


	@FXML public void cancel(){
		Platform.exit();
	}
}

E este é o arquivo DeviceName.fxml:

O erro está nos id’s:

Há uma grade diferença de:

<Button id="prox" mnemonicParsing="false" text="Próximo" onAction="#next"/>

Para

<Button fx:id="prox" mnemonicParsing="false" text="Próximo" onAction="#next"/>

O atributo id serve para especificar as classes do CSS, já o fx:id serve para o FXMLLoader buscar o node (componente) no seu fxml e instanciá-lo no seu controller.

Siga a imagem abaixo para definir o fx:id, no painel code:

erro_fx_id.png830×443 50.1 KB

Dessa forma o que ocorreu foi: O FXMLLoader foi instanciar sua classe DeviceName e não encontrou os nodes prox e name no seu fxml, assim os deixou como null. Em seguida no método initialize você tentou utilizar esses componentes e recebeu uma NullPointerException. :+1:

Opa valeu. Não sabia disso. Porém agora está sendo lançada uma exceção diferente:

A classe CloudServiceSelect é esta:

package com.tkfentretenimento.meusdados.controller;

import java.io.IOException;

public class CloudServiceSelect {

	@FXML private Button finish;
	
	public void Initialize(){
		combo.getItems().addAll("Google Drive","Mega");
		finish.disableProperty().bind(combo.selectionModelProperty().isNotEqualTo("-Selecione-"));
	}
	
	@FXML public void cancel(){

	}
	
	@FXML public void finish() throws IOException{

		new GoogleSignIn();
	}

Classe não encontrada

Se você moveu a classe ou alterou o pacote tem que informar isso para o fxml:

fx:controller="com.tkfentretenimento.controller.CloudServiceSelect"

package com.tkfentretenimento.meusdados.controller;

Thallysson

Muito obrigado pela ajuda. Eu nem percebi que faltou um dos nomes no endereço do pacote. Foi tudo carregado perfeitamente agora.
