Hi Volker,

Here is my JSF Code.

<tx:selectOneChoice label="#{bundle.select}"
                           value="#{checkout.billingAddressId}"
                                id="billingAddressId">
   <f:selectItem itemValue="0"  itemLabel=" --- Select Billing Address ---
"/>
   <f:selectItems value="#{checkout.billingAddresses}"/>


   <f:facet name="change">
      <tc:command action="#{checkout.handleBillingAddressChange}">
        <tc:attribute name="renderedPartially"
value=":page:shipToSitePanel"/>
      </tc:command>
   </f:facet>
</tx:selectOneChoice>

The Panel i.e to be Updated

<tc:panel id="shipToSitePanel" >
   <tx:selectOneChoice label="#{bundle.select}"
                       value="#{checkout.shippingAddressId}"
                       id="shippingAddress" >

       <f:selectItems value="#{checkout.shippingAddresses}"/>
   </tx:selectOneChoice>
</tc:panel>

Varma
