Random Picking an XMLList menuitem

Question

i have this XMLList:

<fx:XMLList id="Generic List" xmlns="">
        <menuitem label="First entry" url="www.aaa.com"/>
        <menuitem label="Second entry" url="www.bbb.com"/>
        <menuitem label="Third Entry" url="www.ccc.com"/>
</fx:XMLList>

I want to randomly select in my combobox (code not displayed) one of these menu item picked randomly. I'm using Flex Builder 4,6.

Thanks for your help.

Have you tried to do something by yourself? Do you want to have a combobox which gets items from this List and sets one of the items as selected? — Anton, Feb 08 '13 at 19:35

Try this:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
           xmlns:s="library://ns.adobe.com/flex/spark" 
           xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

<fx:Declarations>
    <fx:XMLList id="genericList" xmlns="">
        <menuitem label="First entry" url="www.aaa.com"/>
        <menuitem label="Second entry" url="www.bbb.com"/>
        <menuitem label="Third Entry" url="www.ccc.com"/>
    </fx:XMLList>
</fx:Declarations>

<fx:Script>
    <![CDATA[
        import mx.collections.XMLListCollection;
    ]]>
</fx:Script>


<s:ComboBox 
    id="cbEntry" 
    dataProvider="{new XMLListCollection(genericList)}" 
    labelField="@label" 
    creationComplete="{cbEntry.selectedIndex = Math.floor(cbEntry.dataProvider.length * Math.random());}"/>

</s:Application>
