erreur lors de l'utilisation de layout:pager

Version imprimable

Bonsoir,

J'ai un problème avec l'utilisation du tag <layout:pager>.

Je souhaite afficher une liste de 6 éléments, et j'ai fixé un pager de maximum 5 lignes.
Lorsque la page se charge, je reçois l'exception suivante :

Je n'ai aucun problème si l'option maxPageItems est fixée à une valeur supérieur au nombre d'élément dans ma liste, ou si je n'utilise pas le pager.

Il y aurait il des éléments que j'ai oublié de configurer pour pouvoir utiliser le pager ?

voici le code que j'utilise dans ma jsp :

                            </layout:collectionTitle>
                            <layout:collectionTitle title="colis.exp">
                                <layout:collectionItem property="exp"/>
                            </layout:collectionTitle>
                            <layout:collectionTitle title="colis.dest">

OButterlin

non, c'était bien le struts-layout.properties, enfin, pour toi c'est MyDefaultSkin.properties.
Il semble que tu ais un problème de paramétrage de skin.
Quelle version de struts-layout utilises-tu ?

J'utilise la version 1.2 de struts-layout.

Suite à ta remarque sur le struts-layout.properties,je me suis rendu compte que j'étais parti d'un fichier déjà existant que j'ai pris d'une ancienne application en fait.

Il y en a un standard dans le jar de struts-layout que j'ai pris et mis dans mon projet. Résulat : plus aucun problème :ccool:

Merci beaucoup de ton aide.
