Help with t:datalist and command link

[Todd Nine]

I'm trying to iterate over a list and create command links for each
element.  I have the following code

<h:form>
                           <t:dataList var="page"
                                              value="#{
searchBean.searchPages}"
                                              layout="Constant"
                                              rowCountVar="row"
                                              rowIndexVar="index">
                                              <h:commandLink action="#{
searchBean.changePage}" >
                                                  <f:param
name="currentPage" value="#{page.index}"/>
                                                  <h:outputText value="#{
page.displayNumber}"></h:outputText>
                                              </h:commandLink>
                               </t:dataList>
                       </h:form>

I would like the bean value "currentPage" to be set before the action
"changePage" is called.  However when changePage is invoked, the currentPage
variable is not set. What do I need to do so set this value?

Thanks in advance,
Todd
