@rahul – i think it could be you need to cast it as a stroke.

lineseriesInstance.setStyle(“stroke”, Stroke(new ClassFactory(StrokeClass)));

also try it without the class factory and go from there…

lineseriesInstance.setStyle(“lineStroke”, new Stroke(0xFF0000, 4));

ps it may need to be “lineStroke”

@Sam

This line is creating the error:
var label:Label = viewXMLList[i].@label;

It should be something like this:
var label:Label = new Label();
label.text = viewXMLList[i].@label;

hi,

private function onResultHttpService(event:ResultEvent):void
{
var viewXMLList:XMLList = event.result.view;
var len:Number = viewXMLList.length();
var containerWindowManagerHash:Object = new Object();

for(var i:Number = 0; i < len; i++) // Loop through the view nodes
{
// Create a canvas for each view node.
var canvas:Group = new Group();

var label:Label = viewXMLList[i].@label;
canvas.addElement(label);
canvas.percentWidth=100;
canvas.percentHeight=100;
viewStack.addChild(canvas);

// Create a Manager for each view.
var manager:PodLayoutManager = new PodLayoutManager();
manager.container = canvas;
manager.id = viewXMLList[i].@id;
manager.addEventListener(LayoutChangeEvent.UPDATE, StateManager.setPodLayout);
podDataDictionary[manager] = viewXMLList[i].pod;
podLayoutManagers.push(manager);
}

I have been trying to solve this problem so hard but i m not able to solve the error. Please help me….

Hey, I just wanted to say that I had an issue that was solved by replacing this with rawChildren. Thank you very much, you helped me out immensely :)
