The List classes can’t handle XML,
they take arrays of objects. When you had resultFormat=”xml” you
were passing in something that couldn’t be handled.

Subject: [flexcoders] Re: datagrid
does not display http data
Thanks a lot, it was the right idea.
Actually, your piece of code does not compile, but
I wrote the
following that works :
<mx:HTTPService id="catalogContents"
contentType="application/xml"
method="GET"
protocol="http"
url=""
href="http://localhost:8080/protocore/getCatalogContents">http://localhost:8080/protocore/getCatalogContents"
result="setGridData(event.result)"
resultFormat="object"/>
<mx:Script>
var gridData:Object ;
function setGridData(o)
{
gridData = o ;
}
</mx:Script>
<mx:DataGrid id="catalogGrid"
height="100%" width="100%"
dataProvider="{gridData.elements.element}">
I am still confused why my first method did not
work, as I found the
same code in samples applications, like the
"restaurants" one:
<mx:HttpService id="srv"
url="">
<mx:DataGrid
dataProvider="{srv.result.list.restaurant}"/>
I tried the previous code, and it works fine.
with my XML data, it does not work !!! even with
small file.
I'd like to understand...
