Erreur lors de l'utilisation de TableSorter.java

**Frac10** · 20/08/2006, 19h17

Bonjour tout le monde !

Alors voilà, j'utilise le TableSorter de Sun sur une JTable : cela marche convenablement lors de l'affichage initial du tableau mais lorsque je mets à jour ce tableau, j'ai une erreur sur le fichier TableSorter.java (et donc pas sur mon fichier perso) qui apparaît et la mise à jour du tableau se bloque. Par contre si je rafraîchi la fenêtre (en l'agrandissant par exemple), alors le tableau réapparait...

Voilà cette erreur :

Code :

Je n'arrive pas à comprendre d'où cela provient, donc si d'autres personnes ont déjà eu le même problème que moi lors de l'utilisation de ce TableSorter, çà serait sympa de m'éclairer...

J'ai aussi divers souci avec mon TableSorter. Les erreurs apparaissent directement à la première création du tableau.

J'ai essayé de debugger, mais c'est vraiment galère. Apparemment, certain paramètres ne passent pas et on se retrouve a utiliser des valeurs nulles.

Voici une partie de mes erreurs :

Il y a plusieurs versions de ce TableSorter non ?

Vous pouvez nous mettre un lien vers celui que vous utilisez qu'on y voit un peu plus clair ? (notamment pour les numéros de ligne)

**Frac10** · 13/11/2006, 11h33

Tout d'abord merci pour vos réponses.

Pour Satch, voici un lien vers le fichier que j'utilise :

TableSorter.java

Voilà, çà à l'air de venir de cette ligne :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

return getViewToModel()[viewIndex].modelIndex;

Mais je ne comprends toujours pas pourquoi...

**Satch** · 13/11/2006, 12h42

Bizarre.
Je vais peut-être dire n'importe quoi, parce que je ne suis jamais tombé sur une stacktrace comme ça.

Essaye (à tout hasard) de remplacer

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
    public int modelIndex(int viewIndex) {
        return getViewToModel()[viewIndex].modelIndex;
    }

par

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
    public int modelIndex(int viewIndex) {
    	Row r = getViewToModel()[viewIndex];
    	if (r==null){
    		System.err.println("Evidemment que ça merde...");
    	}
        return r.modelIndex;
    }

Si ça ne marque pas que ça merde, essaye (toujours à tout hasard mais j'y crois pas du tout) de remplacer le private modelIndex de la class Row par un protected.

**Bloodscalp** · 13/11/2006, 14h15

J'ai la même version que Frac10, et j'ai la même erreur.

J'ai essayé avec ton code, apparemment r n'est pas null, mais malgré ça il y a une erreur. J'ai exécuté mon code une bonne vingtaine de fois en pas à pas mais je n'y comprend rien.

Erreur lors de l'utilisation de TableSorter.java
