Create a custom exception for a JSpinner

Question

I have two JSpinner components for which I've created a custom exception and it was working very well. Yesterday I modify the spinner in Netbeans, I added a spinner model editor because I wanted only positive numbers.

So now I have only positive numbers but when I put something like -1 it does not display the error message like before, why?

Here's my code:

   public int getAlerte() {
        int res = 0;

        if (Integer.parseInt(jSpinnerTime.getValue().toString()) <= 0 ||
            Integer.parseInt(jSpinnerTime.getValue().toString()) >1000) {
            JOptionPane.showMessageDialog(this, "Time should be between 1 and 1000",
                    "Alert", JOptionPane.ERROR_MESSAGE);
            res = 1;
        }       
        if (res == 0){
            int visperiod = Integer.parseInt(jSpinnerTime.getValue().toString())/2;            
            if (Integer.parseInt(jSpinnerFreqV.getValue().toString()) <= 0 ||
                Integer.parseInt(jSpinnerFreqV.getValue().toString()) > visperiod){
                JOptionPane.showMessageDialog(this, "Visualization frequency should be between 1 and "+visperiod,
                    "Alert", JOptionPane.ERROR_MESSAGE);
            res = 1;
            }

        }
        return res;
    }

Why not just use an [`int` based `SpinnerNumberModel`](http://docs.oracle.com/javase/7/docs/api/javax/swing/SpinnerNumberModel.html#SpinnerNumberModel%28int,%20int,%20int,%20int%29) with appropriate values for the 4 x `int`? — Andrew Thompson, Nov 23 '12 at 03:11
That's what is use in the SpinnerNumberModel. OK for the SSCCE will use it next time, thank you — Pan24112012, Nov 23 '12 at 03:55
*"will use it next time"* Will try to answer next time. ..Though you might also edit *this* question to include an SSCCE. — Andrew Thompson, Nov 23 '12 at 03:56
I second the request for the SSCCE. I for one am not sure what it is you're asking here. — Hovercraft Full Of Eels, Nov 23 '12 at 03:59
So no one can help me, i tried without the visperiod and it's always not working, thx — Pan24112012, Nov 23 '12 at 05:41
*"So no one can help me,"* I expect we can once an SSCCE is posted. *"i tried"* Try preparing an SSCCE. If that very process does not make the problem evident, you will end with a short code that others can use to reproduce the problem. As it is now, all we can do is guess. I'm not good at guessing, and not willing to try on this occasion. — Andrew Thompson, Nov 23 '12 at 05:50
ok i go to learn now about the SSCCE and will get back here thank you — Pan24112012, Nov 23 '12 at 06:12
I really don't understand what is SSCCE but if fixed my problem i go to read the faq about the SSCCE, thank you very much for all — Pan24112012, Nov 23 '12 at 09:41

}

the problem is: when i enter -1 or if click "ok" without entering any thing in the jSpinner it never displays the error message.

i tried to place my getAlert() in the beginning of the code and sitll it didn't work. thx — Pan24112012, Nov 28 '12 at 02:58
