Hi All,

I have an accordion tabbox, each tabpanel contails a list box which is bound using a view model method call:

<tabpanels children="@bind(vm.topLevelNav)">
    <template name="children" var="parent">
        <tabpanel>
            <listbox children="@bind(vm.getChildNav(parent.hierId))">
               <template name="children" var="navItem">
               <listitem> 
                   <listcell label="@bind(navItem.name)"/>
               </listitem>  
               </template>  
            </listbox>
        </tabpanel>
    </template>

</tabpanels>

How do I update only the listbox using the model ? If I do a NotifyChange("topLevelNav"), it refreshes but resets the accordion to its orginal state (top tab expanded) which is not what I want.

Any help appreciated.

Thanks.
