Using xml with datagrid - problem with element attributes ...

Question

Hi,
When i try to set the datafield in a DataGridColumn to an
attribute, ex.: @isPermaLink - the value is not printet in the
datagrid?
My code:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
creationComplete="feedRequest.send()" layout="absolute"
backgroundGradientColors="[#808080, #c0c0c0]">
<mx:HTTPService id="feedRequest" url="
http://kristianthrane.dk/feed"
useProxy="false" />
<mx:Panel x="10" y="10" width="475"
title="{feedRequest.lastResult.rss.channel.title}" id="panel1"
height="531">
<mx:DataGrid id="dgPosts" x="20" y="20" width="100%"
dataProvider="{feedRequest.lastResult.rss.channel.item.guid}"
height="100%">
<mx:columns>
<mx:DataGridColumn headerText="Lande"
dataField="@isPermaLink" />
</mx:columns>
</mx:DataGrid>
</mx:Panel>
</mx:Application>
I hope someone has a tip ....
Best regards,

Hi Kristian,
I'm with some problems, a bit alike yours, but from what I've seen, I would recomend you to see type errors...does the atribute "isPermaLink" inside the "guid" tag, or "title" tag?
My problem is the opposite of what you have... I can place tag attributes in a datagrid, but I can't put in the same Datagrid the tag value. But I have no choice since the feed comes from a public webservice.
My feed is:
<search ver="3.0">
<loc id="BRXX1094" type="1">Aveiro, Brazil</loc>
<loc id="POXX0006" type="1">Aveiro, Portugal</loc>
</search>
<mx:DataGrid x="10" y="53" width="365" id="dgLocation" dataProvider="{wSearch.lastResult.loc}" itemClick="callService(event);">
<mx:columns>
       <mx:DataGridColumn headerText="Localidade" dataField="loc"/> //This doesn't work
       <mx:DataGridColumn headerText="Referência" dataField="@id"/> //This does
</mx:columns>
</mx:DataGrid>
Hope it give you any ideas.
Beste regards
