Flex components at runtime

<mx:Repeater id="rep" dataProvider="{headingData.component}">
        <mx:HBox id="panel" label="{rep.currentItem.title}" 
width="100%" height="100%">
        </mx:HBox>
    </mx:Repeater>

protected function creationCompleteHandler():void
            {
                //Alert.show("init2");
                var components:Array = getComponentsFromXML(xml.component);
                var i:int = 0;
                var n:int = components.length;
                for (i; i < n; i++)
                {
                    panel.addChild(components[i] as DisplayObject);
                }
            }

When i am not placing it under a repeater tag, the components are created from XML, but if i do then the components are not getting created.

Any issues.

Ok, the problem is that the id='panel' inside the Repeater works a bit different than normally. Because this components can be repeated, if you could just set the id, it would be the same for all of them. That's why the name (in your case panel) is actually an array (in this case an array of HBoxes).

If you want to add the child to the first one you need to choose the first array element -

 panel[0].addChild(components[i] as DisplayObject);

---

Do you need many HBox's or many components in it? Usually a Repeater is not used for nested things like in your example. Also, you shouldn't set the 'id' property of your Repeater's child. If you need a complex component you should inherit from HBox and paste that as3 code into it.

Probably, you have to wrap Repeater into HBox. Then you shouldn't add your items into the panel. They should be specified in Repeater's dataProvider.
