nested jquery.tabs

[John]

when I click on the tab_clients the word Clients displays but the inner 
component is not rendered whereas the tab_calendar is fine - why is that?



            <t:jquery.tabs 
t:tabs="tab_dashboard,tab_profile,tab_gallery,tab_colleagues,tab_venue,tab_timetable,tab_work,tab_site"
 t:activePanelId="${panelId}">

                <p:tab_dashboard>
                    <h3>Client Relationship Management</h3>
                    <hr/>

                    <t:jquery.tabs 
t:tabs="tab_calendar,tab_clients,tab_bookings,tab_messages" t:activePanelId="0">

                        <p:tab_calendar>
                           <t:calendar/>
                        </p:tab_calendar>

                        <p:tab_clients>
                            Clients
                           <t:clients/>
                        </p:tab_clients>
