[jboss-user] [JBoss Seam] - Null value sent by s:link in dataTable

Hi, I have a problem when using dataTable tag, I think it's a newbie error but I can't find it ... What I want : - A list of employees - A link to go to a detailed page of the employee To do this, I have this JSF page : <f:view> | <div class="section"> | <h:outputText value="Aucun employé" rendered="#{employes != null and employes.rowCount==0}"/> | <h:dataTable id="employes" value="#{employes}" var="emp" rendered="#{employes.rowCount>0}"> | <h:column> | <f:facet name="header">ID</f:facet> | #{emp.id} | </h:column> | <h:column> | <f:facet name="header">Nom</f:facet> | #{emp.nom} | </h:column> | <h:column> | <f:facet name="header">Prénom</f:facet> | #{emp.prenom} | </h:column> | <h:column> | <f:facet name="header">Action</f:facet> | <s:link id="viewEmploye" value="Voir" action="#{employeCrud.selectEmploye(emp)}"/> | </h:column> | </h:dataTable> | </div> | </f:view> | Here's the method selectEmploye in component employeCrud (CONVERSATION scope) : /** | * | */ | public void selectEmploye(fr.horoquartz.t4.core.employe.VOEmploye selectedEmploye) | { | if (selectedEmploye == null) | { | throw new IllegalArgumentException( | "fr.horoquartz.t4.gui.employe.EmployeCrudActionBean.selectEmploye(fr.horoquartz.t4.core.employe.VOEmploye selectedEmploye) - 'selectedEmploye' can not be null"); | } | try | { | this.handleSelectEmploye(selectedEmploye); | } | catch (Throwable th) | { | throw new fr.horoquartz.t4.gui.employe.EmployeCrudActionException( | "Error performing 'fr.horoquartz.t4.gui.employe.EmployeCrudAction.selectEmploye(fr.horoquartz.t4.core.employe.VOEmploye selectedEmploye)' --> " + th, | th); | } | } | The list of employees works, but when I click on the action link to select an employee, the selectedEmploye parameter is null ! What am I doing wrong ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4068220#...
