Selecting mulitple items in a List programmaticly

Question

Hi everyone,
my list doesn't shows my updates if i select a item programmaticly.
this is an easy example showing my problem:
    <fx:Script>
        <![CDATA[
            import mx.collections.ArrayList;
            import mx.events.FlexEvent;
            [Bindable]
            public var array:ArrayList=new ArrayList();
            protected function view1_initializeHandler(event:FlexEvent):void
                array.addItem("item 1");
                array.addItem("item 2");
                array.addItem("item 3");
                array.addItem("item 4");
                array.addItem("item 5");
            protected function view1_creationCompleteHandler(event:FlexEvent):void
                list.selectedIndices.push(1);
                list.selectedIndices.push(2);
                list.selectedIndices.push(4);
        ]]>
    </fx:Script>
    <s:List width="100%" height="100%" dataProvider="{array}" allowMultipleSelection="true" id="list">
    </s:List>
The list doesn't show any selected items on prgramm start, but if i click for example item 3 or 5 which isnt in the selectedIndices array yet, item 1,2 and 4 becomes visual selected too. Seems like i have too tell the list somehow that it should check its selectedIndices vector if i select an item programmaticly.

Answer 1

thx that helped me ...
but i discovered that there is no need to create a new vector....
  list.selectedIndices.push(1);
                list.selectedIndices.push(2);
                list.selectedIndices.push(4);
list.selectedIndices=list.selectedIndices;
does it as well. im not really doeing anything here, but it seems like u have to call the setter "selectedIndices",  so that some bindings get triggered or some code in this setter gets active and commits the changes. a little bit strange but at least it works
