Bonjour

j'utilise le tag displaytag pour afficher les tableaux.
dans le code suivant :
Code : Sélectionner tout - Visualiser dans une fenêtre à part
1
2
3
4
5
6
7
                    <display:table cellpadding="0" cellspacing="0" name="allUser" defaultsort="1" requestURI="/logonSubmit.do" pagesize="10" sort="list">         
                        <display:column property="login" title="login" sortable="true"/> 
                        <logic:iterate id="role" name="roles">
                            <display:column property="role" title="Roles" sortable="true"/>
                        </logic:iterate>
                        <display:column title="" href="logonSubmit.do" paramId="id" paramProperty="id" paramScope="request"><bean:message key="button.modify"/></display:column>
                    </display:table>
j'affiche la collection "allUser". Mais (hé oui ya un mais) la propriete "roles" est une hashtable et j'aimerais pouvoir afficher ses données dans le tableau, pour cela, j'ai enrobe le tous du tag
Code : Sélectionner tout - Visualiser dans une fenêtre à part
<logic:iterate>
mais ca ne fonctionne pas :
voici l'erreur que j'obtiens :
rg.apache.jasper.JasperException: Exception in JSP: /main.jsp:109

106: <div id="beauxTableaux" >

108: <display:column property="login" title="login" sortable="true"/>
109: <logic:iterate id="role" name="roles">
