ComboBox inside an ItemRenderer keeps going back to initial selectedIndex

Question

Hi,
     Thanks for taking a minute to help me solve this problem. I have the following component, what I want to do, is to save the selectedIndex on the data.selectedIndice variable. I have no trouble with that. The variable saves the correct new selected Index number, but the problem is that, for instance, if the initial selectedIndex was 0, and the user selects the third item of the ComboBox, the ComboBox will go back to selecting the 0 index (the new one was 3) even though that the seleccion.selectedIndex shows that 3 is selected (that's why data.selectedIndice saves 3)
<mx:HorizontalList
        bottom="0"
        backgroundAlpha="0.0"
        id="catalogoOpciones"
        columnCount="3"
        height="80"
        hideEffect="{esconderse}"
        horizontalScrollPolicy="on"
        selectable="false"
        showEffect="{mostrarse}"
        width="100%">
        <mx:itemRenderer>
           <mx:Component>
               <mx:VBox  height="100%" verticalGap="0" horizontalAlign="center" creationComplete="init()">
                   <mx:Label id="titulo" text="{data.nombre}"  textAlign="center" styleName="nombreOpcionDetallePlato" />
                   <mx:ComboBox id="seleccion" dataProvider="{data.opciones}" labelField="label"                          labelFunction="funcionLabelComboBox"  styleName="comboOpcionDetallePlato" change="changeHandler(event)" />
                    <mx:Script>
                        <![CDATA[
                            import menucomponents.clases.OpcionesEvent;
                            import mx.events.ListEvent;
                            import mx.controls.Alert;                                                       
                            public function init():void {
                            public function changeHandler(event:ListEvent):void {        
                                   Alert.show(seleccion.selectedIndex.toString);               //this shows the correct new index selected                                                             data.selectedIndice = seleccion.selectedIndex;               //at the beginning data.selectedIndice was 0, and when I                                                                                                                          change the selectedIdex, data.selectedIndice saves  1                             }                                                                                             correct value, but the ComboBox shows on the screen that                                                                                                                          the selected item is the first one (index 0) and not the                                                                                                                          second one (index 1) AS IT'S SUPPOSED TO                           
                            public function funcionLabelComboBox(item:Object):String {
                                    return item.label + ", $" + item.precio;
                        ]]>
                    </mx:Script>
                </mx:VBox>               
            </mx:Component>
       </mx:itemRenderer>
    </mx:HorizontalList>
Thanks for the help

Answer 1

selectedIndice is public. What's funny is that if I don't use the selectedIndex="{data.selectedIndice}" and I comment the line:
data.selectedIndice = seleccion.selectedIndex
Then the CombBox works just fine. It doesn't go back to the initial selectedIndex. I´m going to solve this using Events and an external Array (Array.length = ComboBox.dataProvider.length) to save the selectedIndex, it's a very un-elegant solution but i think it's going to work. Also I might add, that if I send an Event and catch it outside the List, and try to modify the data.selectedIndice, from the particular ComboBox that I changed, the ComboBox still changes automatically it's selectedIndex.
Thanks for your help.
If some day you think how to solve this, I would really appreciate if you post it here.
