        <logic:present scope="session" name="listButton">          
            <logic:iterate id="listButton" name="listButton" scope="session">
                <bean:write name="listButton" property="from"/>
                <bean:write name="listButton" property="to"/>                 
                <logic:notEmpty name="listButton" property="button">                
                    <bean:write name="listButton.button" property="id"/>
                    <bean:write name="listButton.button" property="key"/>
 
                </logic:notEmpty>
 
            </logic:iterate>            
        </logic:present>

j'ai un petit soucis. il ne fonctionne que lorsque je l'attribut button est null.
En fait la liste listButton contient des object qui eux meme contiennent un objet de type button.

Pouvez vous m'aider merci.

Et quels sont l'erreur et son message ?

Je n'ai pas d'erreur.

j'ai juste ma page qui ne s'affiche pas completement, elle est coupé au milieu.

Par contre qd j'enleve cette partie de code, ca fonctionne
Code:

1 2 3 4 5 <logic:notEmpty name="listButton" property="button"> <bean:write name="listButton.button" property="id"/> <bean:write name="listButton.button" property="key"/> </logic:notEmpty>

Mister Nono

Si elle se coupe au milieu cela signifie que le remplissage du flux HTTP a été interrompu à cause d'une exception.

Peux-tu donner la trace de cette exception ? :?

A+ ;)

Malgré cela, j'ai le meme problem. Je pense plutot que le probleme vient de la page JSP. Je pense m'avoir trompe dans les "logic:iterate", "logic:notEmpty". tu peu y jeter un oeil? Merci

Comment tu defini listButton ?
Quelle est sa classe?

Au passage :

Citation:

Je pense m'avoir trompe dans les "logic:iterate",

Je pense m'être trompé

Essaie plutôt :

Code:

1
2
3
4
                <logic:notEmpty name="listButton" property="button">                
                    <bean:write name="listButton" property="button.id"/>
                    <bean:write name="listButton" property="button.key"/>
                </logic:notEmpty>

Essaie plutôt :
Code:

1 2 3 4 <logic:notEmpty name="listButton" property="button"> <bean:write name="listButton" property="button.id"/> <bean:write name="listButton" property="button.key"/> </logic:notEmpty>
:king: oui c'etait ca, merci beaucoup

Je pense m'être trompé

Désolé, je devais pensé à 2 choses à la fois :aie:

29/06/2007, 08h53
CPI_en_mousse

et maintenant, si je veux integrer les valeurs à un boutton, je fais comme ceci:

Code:

<html:button property="${button.id}" value="${button.key}" title="id"/>

Mais ca ne m'affiche pas les valeurs.
29/06/2007, 08h58
CPI_en_mousse

en fait j'ai trouve :

Code:

<html:button property="${listButton.button.id}" value="${listButton.button.key}" title="id"/>

merci à tous
