In the secureCAController, initialize the agent and launch the application, but when i try to execute one method for example myAgent.getname() return null.
Anyone can help me? I dont know a lot of about javafx sorry if it is a dummy error.
myAgent is an object, that contains a lot of methods.

Maybe this will help you a little..
if you want to pass myAgent to the Controller Class from the Application Class. Your Application class has to look like the following. And you have to make a setter for the myAgent variable in the Controller Class.

javafx fxml LoadException

I am quite new at JavaFx. I am trying to build a simple calculator by following a tutorial . I followed the tutorial step by step . When I run the project , it shows javafx fxml LoadException. I watched some solution relating to this but still I can not fix it. Please help me to fix this error.(Sorry for a long post)
my program files are below

private long number1 = 0;
private String operator = "";
private boolean start = true;
private Model model = new Model();
#FXML
public void processNumbers(ActionEvent event) {
if (start) {
result.setText(""); // set the label(output) screen as blank first
start = false;
}
String value = ((Button) event.getSource()).getText(); // take number 1-9 and convert it into String, import the
// button class otherwise will shows error
result.setText(result.getText() + value);
}
#FXML
public void processOperators(ActionEvent event) {
String value = ((Button) event.getSource()).getText();`enter code here`
if (!value.equals("=")) {
if (!operator.isEmpty()) {
return;
}
operator = value;
number1 = Long.parseLong(result.getText());
result.setText("");
} else {
if (operator.isEmpty())
return;
long number2 = Long.parseLong(result.getText());
float output = model.calculate(number2, number2, operator);
result.setText(String.valueOf(output));
start = true;
}
}
}

Here is your error (in your fxml file):
<Button fx:id="result" mnemonicParsing="false" onAction="#processOperators" prefWidth="50.0" text="/">
<font>
<Font size="18.0" />
</font>
</Button>
This button id is "result" which is also the id of a label. You should either remove this id attribute (I think you missplaced it there) or change it to the one suggested by the tutorial.
UPDATE
This operation is division but you are adding the numbers number1 and number2
case "/":
if(number2==0) return 0;
return number1+number2;
so you should perform a division not addition
case "/":
if(number2==0) return 0;
return number1/number2;
UPDATE 2
Another error I spotted is also here:
float output = model.calculate(number2, number2, operator);
You missed the number1 variable in the calculate method:
float output = model.calculate(number1, number2, operator);

getting value from another package

I wanna get a value from "application" package and use it in "packet" package, but my way doesnt work. I want lblCal in "packet" package to have the same value as loppkcal or lblKcal has in "application" package.
Im sorry if my code looks like shit.
i also mention that arvutaNuppVajutus is the button On Action.
I added comments to code, what i mean ( "application" package has the comment in the bottom).
package packet;

You could change this:
lblCal.setText(nr.arvutaNuppVajutus.loppkcal); //Want same value for this as lblKcal or loppkcal has in "application" package.
to
lblCal.setText(nr.arvutaNuppVajutu());
and change arvutaNuppVajutu() to
public string arvutaNuppVajutu() {
..
return "" + lblKcal;
}

JavaFX DatePicker returning null

So I looked through questions and found this one, which was similar to my problem, but didn't address my issues as I haven't initialized my date pickers in my java file.
I created a date picker. Its fx:id in the fxml file matches its name in the corresponding controller. For some reason, whether I manually type a value or select a date from the calendar, datePicker.getValue() ALWAYS returns null. Can anyone think of why this might be happening?
My code is exactly as the situation I've described here. I have a DatePicker called lowEndDate. I have not initialized it. Upon the click of a button, I want to get its value, but it returns null. Does anyone have any idea why this might be? Perhaps I've missed a step. Thank you.

Code:
public void searchOKButtonClicked(ActionEvent e){
boolean searchComplete = false;
User currentUser = LoginController.currentUser;
if((lowEndDate.getValue() == null) && (highEndDate.getValue() == null) && ((tags == null) || tags.getText().trim().isEmpty())){
Alert alert = new Alert(AlertType.ERROR);
alert.setContentText("Oops! At least one field is required to search.");
alert.show();
}
}
The trouble here: lowEndDate and highEndDate are ALWAYS null, regardless of input.

Sara, I've tested your fxml file using this simple project
Main
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample2.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Controller
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Alert;
import javafx.scene.control.Alert.AlertType;
import javafx.scene.control.DatePicker;
public class Controller implements Initializable {
#FXML
DatePicker lowEndDate;
public void searchOKButtonClicked(ActionEvent e){
Alert alert = new Alert(AlertType.ERROR);
alert.setContentText("Oops! At least one field is required to search. " + " " + lowEndDate.getValue());
alert.show();
}
#Override
public void initialize(URL arg0, ResourceBundle arg1) {
// TODO Auto-generated method stub
}
}
In your fxml, I've changed the naming in the two datepickers, I think that lowEndDate must be above highEndDate
<DatePicker fx:id="lowEndDate" layoutX="20.0" layoutY="92.0" promptText="dd/mm/yyyy" />
<DatePicker fx:id="highEndDate" layoutX="20.0" layoutY="148.0" promptText="dd/mm/yyyy" />
This is the result that I've obtained when I introduce a date
Maybe you have an error in another part of your controller but the datepickers seem to work fine.
