[flexcoders] custom renderer for list

[Cliff Meyers]

I'm having some problems getting a custom renderer to work for a List.
 All I'd like to show for each item are mx:Image and mx:Label tags. 
However I'm having some problems getting it to work...

First off I'm not sure if a rowRenderer or cellRenderer is appropriate
here.  The documentation seems to indicate that a rowRenderer is only
necessary if a different "template" needs to be used from row to row. 
This isn't the case in this situation since each item in the list just
needs an image and accompanying label.

Here is the code for my renderer:

<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:mx="http://www.macromedia.com/2003/mxml";>
        <mx:Script>
                <![CDATA[
                        [Embed(source="images/taxonomy/legal.png")]
                        var appSymbol:String;
                        
                        function setValue( str:String, item:Object, sel:Boolean 
) : Void
                        {
                                myLabel.text = item.name;
                                myImage.source = appSymbol;
                        }
                ]]>
        </mx:Script>
        <mx:Image id="myImage" />
        <mx:Label id="myLabel" />
</mx:HBox>

and here is the invoking page:

<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="http://www.macromedia.com/2003/mxml";>
        <mx:Model id="myTaxonomies" source="faketaxonomy.xml" />
        
        <mx:Label text="Select a category to filter the application list." />
        
        <mx:List
                id="categoryFilter" 
                multipleSelection="true" 
                rowCount="4" 
                dataProvider="{myTaxonomies.taxonomies}"
                rowRenderer="components.categoryFilterRowRenderer" />
</mx:VBox>

When I invoke it as a rowRenderer, the images appear but the text
doesn't.  When I invoke it as a cellRenderer, the list is blank. 
Lastly here is the content of my XML file:

<?xml version="1.0" encoding="utf-8"?>
<taxonomies>
        <taxonomy name="Legal" icon="legal.png" />              
</taxonomies>

Any help that anyone could pass along would be greatly appreciated.  Thanks! :)
