                <h:inputText id="lloyds" value="#{imvessel.scacCode}"/>
                <s:link value="Select" view="/admin_configuration_transportation/IcCarrierList.xhtml">
                            <f:param name="from1" value="transportation_ocean/ImVesselList"/>
                    </s:link>
            </s:decorate>
            
            </h:panelGrid>
           </rich:simpleTogglePanel>

where i select the SCAC from other page .

                  <s:link view="/#{empty from1 ? '' : from1}.xhtml" 
                             propagation="#{empty from1 ? 'none' : 'default'}"
                               action="#{carrierAction.selectCarrier}"     id="voyage">
                             <h:graphicImage value="/img/Select.png" style="border:0" length="15" width="15"/>
                             <f:param name="scacCode" value="#{_icCarrier.scacCode}"/>
                   </s:link>

The problem is when i return to the page after selecting the value ,The values in the rest of the feilds disappear what do i do to retain the state .
