Problema em abrir um novo fxml apartir da mesma scena

LostSpirit · Junho 21, 2019, 12:51am

bom estou tentando abrir um fxml da mesma tela apartir de um button:

private StackPane rootPane;
@FXML
private void handleButtonAction(ActionEvent event) {

}

@FXML
private void validar(ActionEvent event) {
valida2();
}

private void xd(){
try {
   StackPane pane = FXMLLoader.load(getClass().getResource("../Views/Principal.fxml"));
    rootPane.getChildren().setAll(pane);
} catch (IOException ex) {
    Logger.getLogger(LoginC.class.getName()).log(Level.SEVERE, null, ex);
}    
}

public void valida2() {
String Login = jLogin.getText(), Senha = jSenha.getText();
Usuario u = new Usuario(Login, Senha);
UsuarioDAO dao = new UsuarioDAO();
if(dao.validarSenha(u)==true){
xd();
}else{
Alerts a = new Alerts();
a.alertSenhaErrada();
}
}

LostSpirit:

private void xd(){

try {
   StackPane pane = FXMLLoader.load(getClass().getResource("../Views/Principal.fxml"));
    rootPane.getChildren().setAll(pane);
} catch (IOException ex) {
    Logger.getLogger(LoginC.class.getName()).log(Level.SEVERE, null, ex);
}

Problema resolvido

faltava colocar nome do pane : rootPane no outro fxml.
