Hello there!

Im trying to use the listShuttle to add roles to a User Entity, but im getting problems when when i execute the action to persist the user.

As far as i understood, the var attribute on the listShuttle RichFaces component is used as a list and to get the value to the columns on the selection tables. When i execute the command registerUser i get this exception:

javax.faces.FacesException: javax.el.PropertyNotFoundException: /registerUser.xhtml @42,63 value="#{rolesShuttle.name}": Property 'name' not found on type java.lang.String

here is the xhtml file;

<ui:define name="body">

 <rich:panel>
 <f:facet name="header">registerUser</f:facet>

 <h:form id="registerUserForm">
 <div class="dialog">
 <h:panelGrid columns="4" rowClasses="prop"
 columnClasses="name,value,nameRigth,valueRigth">

 <h:outputLabel for="name" value="#{messages['registerUser.name']}" />
 <h:inputText id="name" value="#{registerUser.name}" required="true" />

 <h:outputLabel for="password" value="#{messages['registerUser.password']}" />
 <h:inputSecret id="password" value="#{registerUser.password}" required="true" />

 <h:outputLabel for="mail" value="#{messages['registerUser.mail']}" />
 <h:inputText id="mail" value="#{registerUser.mail}" required="true" />

 <h:outputLabel for="fullName" value="#{messages['registerUser.fullname']}" />
 <h:inputText id="fullName" value="#{registerUser.fullName}" required="true"/>

 <rich:listShuttle
 var="rolesShuttle" listHeight="300" listWidth="200"
 sourceCaptionLabel="Available Items"
 sourceValue="#{registerUser.rolesList}"
 targetCaptionLabel="Currently Active Items"
 targetValue="#{registerUser.rolesSelection}">

 <rich:column>
 <h:outputText value="#{rolesShuttle.name}"></h:outputText>
 </rich:column>
 </rich:listShuttle>

 </h:panelGrid>
 </div>
 <h:commandButton id="registerUser" value="registerUser!" action="#{registerUser.registerUser}"/>

 </h:form>

 </rich:panel>

</ui:define>

</ui:composition>

Why when the page is rendering there is no problem with value rolesShuttle.name, but when is executing the action a exception is raised?

Thanks a lot!
