Thanks. Totally forgot about the resultFormat. So used to using RemoteObjects, 
but we have Blue Disaster(opps, Dragon) here at the U.

                                Hi Wally,

    Any particular reason you are not setting a resultFormat on your

mx:operation? For example:

<mx:operation name="service" resultFormat="object"

result="serviceResult(event)"/>

I am having fits trying to figure out how to use the information

coming back from a webservice. I created a web service call in my code:

    <mx:WebService id="storyGateway" 
wsdl="http://www2.med.umich.edu/prmc/media/newsroom/stories.cfc?wsdl";

fault="Alert.show(event.fault.message,'Story Gateway

Error')">

        <mx:operation name="listBySubject" result="buildBookHandler(event)"

fault="Alert.show(event.fault.message,'Story Gateway

Error')" />

    </mx:WebService>

It returns the data as requested, I can see it in my debugging, but I

cannot figure out how to set it to a variable and then call the various

elemenets (linkText, story, photo, defaultLogo)

I tried to set it to a variable as an ArrayCollection:

            [Bindable]

            public var storyFeed:ArrayCollection = new

ArrayCollection();

public function buildBookHandler(e:ResultEvent):void {

                storyFeed = e.result as ArrayCollection;

              for (var i:uint = 0; i < e.result.data.length;

i++){

                    ...

                    //Story Area

                    var storyArea:TextArea = new TextArea();

                    storyArea.text = storyFeed.getItemAt(i).story;

                    storyArea.wordWrap = true;

                    storyArea.height = 550;

                    storyArea.width = 400;

                    storyArea.editable = false;

                    magPage.addChild(storyArea);

                    storyArea.x = 0;

                    storyArea.y = 25;

                   ...

                }

                rssMag.flipOnClick = true;

            }

But still getting errors..

TypeError: Error #1009: Cannot access a property or method of a null

object reference.

    at RSSMagazine/buildBookHandler()[D:\wkolcz\My

Documents\Flex Builder 3\RSSMagazine\src\RSSMagazine.mxml:36]

Line 36 is:

storyArea.text = storyFeed.getItemAt(i).story;

Help!
