        <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.

[willoi]

Et quels sont l'erreur et son message ?

[CPI_en_mousse]

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 :

                <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 ?
