Multiple initializers for property dataProvider

Question

All I'm trying to do is display xml data from a Rails application in a list., but it doesn't like this:
                    dataProvider="{student_requests.student_request}"
It tells me "multiple initializers for property dataProvider".
Any idea of how to address this? Thanks.

Answer 1

Yeah I removed it but still no data.
I was referencing this:
http://www.adobe.com/devnet/flashcatalyst/articles/building_datacentric_app_flas hcast_flashbuilder_03.html
But he uses Coldfusion, and I tried using the HTTP to connect to data, but the data would never display properly. So I was forced to use HTTPService declarations, which prompted me to change code around. And this was one of it. His approach generated this:
            <s:List skinClass="components.DataList3" x="65" y="96" change="list_changeHandler()" id="list1" creationComplete="list1_creationCompleteHandler(event)" dataProvider="{TypeUtility.convertToCollection(indexResult.lastResult)}" labelField="student_request">
            </s:List>
