Hello guys,

I try to use the <a4j:param> tag inside an <a4j:commandlink> to store a Value in my Userbean! But the Value printed out from function remove() (confirmPane) is always 0!

heres my code(Page):

    <rich:dataTable value="#{usermanager.userList}" var="users"

        </rich:column>

            </f:facet>
            <h:outputText value="#{users.active}"/>
        </rich:column>
        <rich:column>
            <a4j:commandLink value="delete" styleClass="no-decor" execute="@this"
                    render="@none" oncomplete="#{rich:component('confirmPane')}.show()">
                <a4j:param name="userindex" value="#{it.index}"
                           assignTo="#{usermanager.currentUserIndex}" />
            </a4j:commandLink>
            </rich:column>

    </rich:dataTable>

<a4j:jsFunction

name="remove" action="#{usermanager.remove}"

render="table" execute="@this"

oncomplete="#{rich:component('confirmPane')}.hide();"

<rich:popupPanel id="confirmPane" modal="false" autosized="true">

Are you sure you want to delete the row?

<a4j:commandButton value="Cancel" onclick="#{rich:component('confirmPane')}.hide(); return false;"/>

<a4j:commandButton value="Delete" onclick="remove();return false;"/>

<h:messages style="color: red" globalOnly="true"/>

</rich:popupPanel>

and the bean:
