[flexcoders] Newbie alert - Trying to populate combobox w. httpservice

[Mark Bjærgager]

Being a newbie at Flex2 (and AS) I am trying to populate a combobox with
specific values from a HTTPService.

The xml is retrieved and the datagrid works fine, but the combobox dont
display the data.
What I'd like is to have {title} as label and {edition} as value - later I
will be using the selected value as a parameter for a new http call.

Any help will be really appreciated.

thanks,
Mark

Here's my code :
<?xml version="1.0"?>
<!-- Simple example to demonstrate the HTTPService tag. -->
<mx:Application xmlns:mx=" http://www.adobe.com/2006/mxml";
   creationComplete="xmlEdition.send();">
   <mx:HTTPService
       id="xmlEdition"
       url=" http://flex2.dk/mark/xml/ddt/xmlEdition.xml";
       useProxy="false"
       showBusyCursor="true" />
   <mx:Panel title="DDT" height="95%" width="95%"
       paddingTop="10" paddingBottom="10" paddingLeft="10"
paddingRight="10">
       <mx:DataGrid id="dgPosts" height="50%" width="75%"
           dataProvider="{xmlEdition.lastResult.action.item}">
           <mx:columns>
               <mx:DataGridColumn headerText="Posts" dataField="edition"/>
               <mx:DataGridColumn headerText="Date" dataField="title"/>
           </mx:columns>
       </mx:DataGrid>
       <mx:ComboBox id="cbEdition" dataProvider="{
xmlEdition.lastResult.action.item}"  />
   </mx:Panel>
</mx:Application>
