Bad selectedIndex and selectedItem returned on List component

[Google Code Exporter]

What steps will reproduce the problem?

import com.bit101.components.List;

var l:List = new List(this, 5, 5, [2, 3, 4, 5, 6, 7, 8, 9, 10] );

l.addEventListener(Event.SELECT, onSelectHandler );

function onSelectHandler(pEvt:Event):void
{
    trace("item = ", l.selectedItem, " / index = ", l.selectedIndex );
}

Scroll the list and select an item, you always have the last visible itemforn 
the first 5 visible items.

What is the expected output? What do you see instead?

the trace output is fine for the 5 visible item, but if you scroll the trace 
output is wrong.

What version of the product are you using? On what operating system?

minimalcomps_0_9_6.swc

Please provide any additional information below.

In order to have the correct index, you just need to add the offset (scrollbar 
value) when register the selectedIndex.

Here's the correct version of the onSelectMethod in the List Class :


protected function onSelect(event:Event):void
        {
            if(! (event.target is ListItem)) return;


            var offset:int = _scrollbar.value;

            for(var i:int = 0; i < _itemHolder.numChildren; i++)
            {
                if (_itemHolder.getChildAt(i) == event.target)
                {
                    _selectedIndex = offset + i;
                }
                ListItem(_itemHolder.getChildAt(i)).selected = false;
            }
            ListItem(event.target).selected = true;
            dispatchEvent(new Event(Event.SELECT));
        }
