[Struts-layout 1.3] Tri Date n'importe comment sur layout:collection

Hello les gens;
Tout est dans le titre. Je viens de me rendre compte que le tri des colonnes contenant un type Date dans un

Code:

---

<layout:collection />

---

sont trié bizarrement.
Voici mon code:
ma jsp:

Code:

---

1 2 3 4 5 6 7 8 9 10

<layout:collection model="fixedHeader" width="100%" align="center" id="iteration" indexId="index" sortAction="client" styleClass="impaire" styleClass2="paire" height="332" bundle="labelScreen" emptyKey="page.struts_layout.collection.vide" property="list" name="form" styleClass="FORM">   <layout:collectionItem sortable="true" type="date" title="page.admin.myBills.column.label.date.generation" property="genDate" />

---

Sur mon action les beans sont rempli comme suit:

Code:

---

1 2 3 4

Form beanForm = (Form) form; Random random = new Random(); MonBean dataBean = new MonBean(); dataBean.setGenDate(new Date(random.nextInt()));

---

Et voici la class responsable du formattage:

Code:

---

1 2 3 4 5 6 7 8 9

public class MonFormatter extends DispatchFormatter {   public String date(Object in_date, PageContext in_pageContext) { Date lc_date = (Date) in_date; SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/MM/yyyy"); return simpleDateFormat.format(lc_date); }   }

Merci pour toutes vos contributions.

Ça serait bien de préciser ce que tu entends par "trié bizarrement".

As-tu déclaré la classe MonFormatter dans le fichier Struts-Layout_default.properties dans la clé formatter.class, comme indiqué dans les features du site de Struts-Layout.

Tres bonne question. Il me semble que les jours et mois sont tries correctement, les annees quand a elles "subissent" un group by ou sont triees inversement a l'ordre des jours et mois. Un exemple pour illustrer mes propos:
Un tri ascendant:
01/01/1990
02/01/1990
01/02/1990
01/01/1989
02/01/1989

ça n'est pas du tout ça. Je n'arrive pas cerner la logique de tri de ces dates. C'est un peu au petit bonheur la chance ??!? :aie:

J'ai fait un test hier chez moi, effectivement, c'est du gros n'importe quoi 8O
Je regarde dans le code pour savoir ce qu'ils font exactement, je te tiens au courant...

fr.improve.struts.taglib.layout.sort.BeanComparator

Il ne font pas plutôt appel à la fonction arraySort() du js javascript.js ? Mon tri à moi est réalisé côté client.

A priori non, si tu regardes le lien associé à l'icône de tri, tu devrais trouver un lien sur sort.do?layoutCollection=...

Essaies d'ajouter un

sortAction="client"

Il l'a déjà (si tu regarde le code fourni)...

Eh ben, j'suis fatigué moi... :aie:

J'ai bien un sortAction="Client", mais d'un autre côté, je suis dans un <layout:pager>, ça change un peu...
Toi, tu as une collection sans pager ?

Oui sans pager.

Après investigations, ce n'est pas javascript qui pose problème mais la classe CollectionTag de la bibliothèque Struts-Layout.
Le problème vient de l'utilisation de groupe <layout:collectionTitle> qui fausse l'indice de la colonne dans l'appel de la fonction javascript.

Sans collectionTilte, ça marche...

Je regarde s'il y a moyen de corriger la classe...

A+

Voilà, si tu intègres cette classe à ton projet, ça devrait fonctionner...

Sans collectionTilte, ça marche...

pas chez moi mais je veuw bien essayer avec ta classe.

Citation:

Voilà, si tu intègres cette classe à ton projet

---

je fais comment ? Je régénère un jar en remplaçant dans les sources la classe CollectionTag par la tienne?

Tu crées un package fr.improve.struts.taglib.layout.collection dans src, tu crées une classe CollectionTag dans ce package et tu colles le contenu que je t'ai fourni dedans.
(elle sera prioritaire sur celle du jar)

(elle sera prioritaire sur celle du jar)

Je me coucherais moins bête ce soir.
Par contre quel version as tu de struts-layout ? Il me manque les deux interfaces:
"fr.improve.struts.taglib.layout.util.IFilterableHeaderRenderer" et
"fr.improve.struts.taglib.layout.util.ISelectionCellRenderer"

Je l'ai faite sur une base de struts-layout 1.4.2... Tu utilises la 1.3.x ?

yep

Essaye celle-là (mais je ne peux pas la tester)

Tu utilises une variable sortPoperty que tu ne défini nul part.
J'ai vu le change log de la version 1.4 et ça ne vaut (pour moi) pas le coup de passer en 1.4

Je regarderai ce soir calmement... Je te tiens au courant...

Finalement, ce n'était pas grand chose...

Visiblement nous n'avons pas le même souci, mon problème est toujours d'actualité, sachant que je n'utilise pas de <collection:title> ni de pager. :cry:

Quand tu survoles l'icône de tri, qu'est ce qui s'affiche dans la zone status de la fenêtre ?

Code:

---

javascript:arraySort()

---

Mais avec quels paramètres ?

Quatre paramètres:
Le premier est toujours à 1.
Le seconde est le numéro de la colonne en commençant par 0.
Le troisième j'ai l'impression que c'est le nombre total de lignes contenues dans ma collection.
Le quatrième est toujours à 10.
Ce qui nous fais:

Code:

---

javascript:arraySort(1,0,100,10)

---

pour le tri de la première colonne d'une collection contenant 100 beans, que ce soit pour un tri ascendant ou descendant.

Et l'indice de la colonne correspond bien à ta demande ?

Si oui, quel navigateur utilises-tu et quelle version de struts-layout précisément ?

Oui.

IE 8 et FF 3.5.8 et le résultat est similaire.
Pour la version struts-layout c'est une 1.3 je ne saurais être plus précis.

Peux-tu joindre le source de la page sur le navigateur ?

Bien sur.
source.txt
Je n'ai aucune erreur javascript.

Ça semble correcte à première vue, bizarre 8O

Tu as déjà récupéré la dernière version de struts-layout 1.3 sur leur site ?

J'ai le souvenir d'avoir récupéré une version stable.

Peux-tu vérifier ?
En passant, peux-tu également montrer le fichier struts-layout.properties ?
