Hi, we are using menu with sub menus which is implemented using JSF but forward navigation is working fine but backward navigation is not working please help in this.

this is my header jsp:

<ul>
    <li class="bottomline">
        <h:commandLink value="General Ledger Mapping"
                       action="#{fyeSelection.getGLMappingSelection}"></h:commandLink>
    <li class="bottomline">
        <h:commandLink value="File Upload" action="#{fyeSelection.getFYEUploadScreen}"></h:commandLink>
    </li>
    <li class="bottomline">
        <h:commandLink value="Provision Lock Down" action="#{fyeSelection.getProvisionScreen}"></h:commandLink>
    </li>
    <li class="bottomline">
        <h:commandLink value="Copy Provision for Tax Return"
                       action="#{fyeSelection.getCopyProvisionTaxScreen}"></h:commandLink>
