I can not change the text of the button created in FXML. Even though I put it inside initialize(... butao.setText("..."); it does not change.

What do I do?

PersonController, intializable:

@Override
public void initialize(URL arg0, ResourceBundle arg1){...

    adicionareditarnovadivida.getItems().addAll("Adicionar","Editar","Nova Divida","Imprimir Carnê");
    adicionareditarnovadivida.getSelectionModel().select(0);
...}

PersonController, ComboBox Method:

@FXML
private void adednd(ActionEvent event){
    String saf = adicionareditarnovadivida.getSelectionModel().selectedItemProperty().get();
    System.out.println(saf);
    switch(saf){
    case"Adicionar":
        adicionar.setText("Adicionar");
        imprime.setDisable(true);
        clientes.setDisable(true);
        rg.setDisable(false);
        cpf.setDisable(false);
        endereco.setDisable(false);
        break;
    case "Editar":
        adicionar.setText("Editar");
        imprime.setDisable(true);
        clientes.setDisable(false);
        rg.setDisable(true);
        cpf.setDisable(true);
        break;
    case "Nova Divida":
        adicionar.setText("Nova Divida");
        imprime.setDisable(true);
        clientes.setDisable(false);
        rg.setDisable(true);
        cpf.setDisable(true);
        endereco.setDisable(true);
        break;
    case "Imprimir Carnê":
        imprime.setDisable(false);
        clientes.setDisable(false);
        break;
    default:
        SI.AlertDialog(stage, "Erro Desconhecido.", AlertType.ERROR);
    }
}

PersonController, Button Method:

 @FXML  
 private void Adicionar(ActionEvent event) { ...
                switch(adicionar.getText()){
                    case "Adicionar":
                        TextFieldMascaras.adicionar(nome, divida, pagamento,compradata, vencimento, cpf, rg,telefone, endereco, produtos,stage,carne.getText());
                        break;
                    case "Editar":
                        TextFieldMascaras.editar(nome, divida, pagamento, compradata, vencimento, carne.getText(), stage,produtos);
                        break;
                    case "Nova Divida":
                        TextFieldMascaras.editar(nome, divida, pagamento, compradata, vencimento, carne.getText(), stage, produtos);
                        break;
                    case "Imprimir Carnê":
                        TextFieldMascaras.Imprimir(nome, divida, pagamento, compradata, vencimento, carne.getText(), stage, produtos);
                        break;
                    default:
                        SI.AlertDialog(stage, "Erro Deconhecido!!", AlertType.ERROR);
                    }
    ...}

What's wrong?

Button:

    private Button adicionar = (Button) getFXMLField((AnchorPane)pane, "Adicionar");

And MainApp:

Problem when requesting AJAX DELETE sending JSON Image Upload saved only first image in the database

score 2 · Accepted Answer

I had this same problem to load a properties file when opening the screen, I do not know if it is the best way to solve it, but it follows the code:

private Node getFXMLField(AnchorPane ap, String fxid) {
    ObservableList<Node> fxmlFields = ap.getChildrenUnmodifiable();
    for (Node field : fxmlFields) {
        if(field.getId().equals(fxid)){
            return field;
        }
    }

    throw new IllegalStateException("Campo " + fxid + "não existente");
}

With Node you can cast to any javafx component and then set whatever values you want.

An example:

Button button1 = (Button) getFXMLField(formPai, "nome do botão");
button1.setText("xanana");
