Displaying user feedback with a4j:?

[Dan Acuff]

I have the following code, how do I improve it by adding code to display to the user that the shipment method was updated to X shipping method? (there are 4 ship method choices in the radio button code; Standard, Second Day, Next Day, and Choose every time.)

<a:support is actually the name-space we use for A4J:

  <div id="shipmentMethodpanel" class="section_block">
<h2><span>Your Preferred Shipping Method</span></h2>
<h:selectOneRadio id="shipmentMethodCode"
	value="#{customerSession.customer.defaultShipmentMethodCodeId}"
	layout="pageDirection">
	<f:selectItems id="shipmentMethodTypes"
		value="#{webstoreContext.getDefaultShipmentMethods(customerSession.store)}" />
	<a:support event="onchange" ajaxSingle="true" />
</h:selectOneRadio>
</div>

Hello,

You could modify the getDefaultShipmentMethods method, to return
selectItems whose value is shomething like a ShipmentMethod bean (Object), rather then a shipmentMethodCodeId. The ShipmentMethod bean can contain a property (via something like getName) name, that contains the name besides a property shipmentMethodCodeId. That way you'll have access to both.

Then you have to add a property customerSession.customer.defaultShipmentMethod of type ShipmentMethod to your customerSessoin.customer bean.

Something like (not checked for syntax errors btw):

<h:outputText id="shipmentMethodName" value="#{customerSession.customer.defaultShipmentMethod.name}" />
<h:selectOneRadio id="shipmentMethodCode"  
     value="#{customerSession.customer.defaultShipmentMethod}"  
     layout="pageDirection">  
     <f:selectItems id="shipmentMethodTypes"  
         value="#{webstoreContext.getDefaultShipmentMethods(customerSession.store)}" />  
     <a:support event="onchange" ajaxSingle="true" reRender="shipmentName" />  
</h:selectOneRadio>
