Flex viewstack addchild dynamically without recreating each child

Question

I have a viewstack with a repeater inside to create each child. Soemthing like that:

    <mx:ViewStack width="100%" height="100%" >
    <mx:Repeater id="myrepeater" dataProvider="{myDataProvider}">
    <mx:HBox width="100%" height="100%" >
    ---view content goes here---
    </mx:HBox>
    </mx:Repeater>  
    </mx:ViewStack>

When I add an item to the dataprovider, it creates the new child, but it also reloads all the other children, which I don't want. How do I prevent Flex from recreating the component when it adds a child?

Thanks.

I'm not sure how helpful this is; but don't use a repeater; XML wasn't designed for loops. Re-write your code in ActionScript.. — JeffryHouser, Sep 18 '12 at 15:42

You can't do it "incrementally" with a Repeater, you should do it programmatically instead using the method addChild() which belongs to Container hence it's inherited by, for example, the HBox at the first level inside your Repeater,

If you can use Flex 4 or higher, then use a DataGroup or a List instead of a Repeater. Everything will just work better.

Otherwise, you can try setting recycleChildren=false on the Repeater.
