[flexcoders] XML List problems

[markcavins]

I have had some help from some others on this issue but the battle
continues and I am perplexed as to why this might be happening.

I am grabbing a HTTPService from my site

<mx:HTTPService  id="tempXML"
url="https://mysite.net/interface.php?action=showopen&amp;operation=showassets&amp;format=xml&amp;opstatus=crit";
/>

and displaying it in a TileList

<mx:TileList dataProvider="{tempXML.lastResult.asset.fleet}" 
                width="344" backgroundColor="#000000" color="#ff0000" 
fontSize="27"
borderColor="#000000" columnWidth="300" rowHeight="50"
themeColor="#808080" fontWeight="bold" allowMultipleSelection="true" 
id="TileList1" height="0" y="202" x="178"/>
                
and then refreshing the data every 5 minutes or when a user pushes a
button.

before I was trying to call the data with a mx:XML and the data was
displaying but the data would not refresh. Looking through the docs it
seems that that is the expected response. changing to the Service
request I can look through firebug and see that the request is being
made and that the server is returning the proper xml but now the
TileList is not displaying any information.

I have tried to look through the docs to see what might be the cause
but not solution has presented itself.
