Does anyone here use JavaFX? I have a little trouble figuring out how to make the second form work

[sick roost]

Even after I use the FXMLLoader to get the first form through its designated controller, it keeps telling Exception whenever I press the button prompted to transfer me to the next form

Could you show the code for this and the error if possible.

[sick roost]

Want me to zip it or just ss it?

It's like, 1 main app, 2 controllers for their 2 fxml files

[pallid steeple]

You can just send it here in code blocks, or use pastebin

Okay so
I tried doing a separate calculator to do a program that would do both gross and net

public class CalcuServiceImpl {

static CalcuServiceImpl calcService = null;

public static CalcuServiceImpl getCalcuService(){
    if(calcService == null)
        calcService = new CalcuServiceImpl();
    return calcService;
}

Calcu calcu;
public CalcuServiceImpl(){
    calcu = new Calcu();
}

public Calcu get(){
    return calcu;
}

}

2. public class Calcu {
   int num1 = 0;
   int num2= 0;
   int sum= 0;
   } ```

For what I tried, it seemed to have no errors

Second form goes kapoot everytime I press the prompt where it's supposed to output it

[sonic stirrup]

Could you send the error code

[sick roost]

Which one, cuz it doesn't read any errors for me
You mean the error it outputted?

[sonic stirrup]

Yeah mb just woke up

Are you attempting to create a new window or just call this class?

[sick roost]

Well, create a new one

it's either i didn't put some of the Calcu codes on my first controller or I forgot to put a get and set for it

[sonic stirrup]

Would you mind sending the .java and fxml files to me so I can quickly run it on my end.

If not, could you show the code which your creating the new window.

[sick roost]

Hold on

[sonic stirrup]

Think I found the issue, here's how I did it so you know how to debug this type of issue.

Firstly I ran and tested the program until I hit the error point, from then, I looked to the bottom of the terminal and looked for the highlighted blue section, this tells us the error is line 30 in first controller.

Above that we can see the actual error is that the field **hoursWorkedField **was null. To fix this I just had to go rename this variable to the one that is found in your FXML which is hoursField, after that it ran without the error and displayed the second window.

Let me know if this fixes the problem.

[sick roost]

Wait, hoursField? How come?

It's just a public Text field

[sonic stirrup]

If you have a look at your PrimaryController FXML file, you will see a highlighted field at the bottom on line 38.

That is because the FX:ID="hoursField" hasn't got a reference in controller, so you were referencing a ID that did not exist in your FXML.

[sick roost]

It couldn't have been the only error

[sonic stirrup]

Everything worked fine for me afterwards

try it on your end and see if it works

You can make it private, but would then need to add the @FXML annotation to make it visible to JavaFX.

But to explain a bit more clearly:

Your variable named hoursWorkedField would work perfectly fine, it's name was simply not correctly referencing the FX:ID name you set in your FXML file. As such, when the program attempted to get a value from that textfield it could not, since no textfield was created with that name, so we got a NullPointerException error each time.

But, if we change the hoursWorkedField to match the name you put in your FXML file which is hoursField you will then be able to use the field values in the code.

[sick roost]

Ohhhh
Okay, looking back at my previous prompt that makes sense

I'll go ahead and try for myself

Thank you

Shouldn't have said it too soon

[sonic stirrup]

Did you run into an issue?

[sick roost]

No no, it's just this lol
I actually haven't ran with the code yet, I went to eat a bit

[sonic stirrup]

Ah, mb, misunderstood what you said.

[sick roost]

No worries

I went back and did what you asked

And I got into a bit of trouble with the back button and the output is all wrong

The problem might be the same as for the calculating one

Okay, scratch that, I figured out the Back Button

The calculating one needs to be reconfigured because it just outputs zeroes

[sonic stirrup]

The back button is a similar issue. You are referencing a button back but you are not referencing the one inside the FXML file, you will need to add a FX:ID to the button and it should fix that problem.

[sick roost]

Yeah, I figured that one out
Any issues with the calculating whatsoever?

[sonic stirrup]

From a quick glance I don't think your actually setting a value to the values in your Calcu class, or at least not the values the user inputs, have a look at that for now.

[sick roost]

I reevaluated all of the codes from Calcu and CalcuImpl

If it means I have to output a user's role and payment, I would have to ditch both of those scripts to be able to put both calculations and category at the same time

It's not my intent to remove it completely, but I think this works better
