onItemSelectedChanged fires twice when changing from one item to another. Is this a bug?

We are using ActiveWidgets 2.5 alpha2 Version.

We have a radio with four items (0,1,2,3). If we click in item 2 coming from any other item, then onItemSelectedChanged fires twice and we get the alert '2' twice. We get the same behaviour with onItemSelectedChanging

RB.onItemSelectedChanged = function()
{
alert(RB.getSelectedItems());
}

We think that if we go from 0 to 2:
RB.onItemSelectedChanging shoud fire once and RB.getSelectedItems()
value should be 0 and we should have the posibility to cancel.
RB.onItemSelectedChanged shoud fire once and RB.getSelectedItems()
value should be 2 (no posibility to cancel since already changed)

Is this the logic intended in AW? Is the behaviour we are getting a bug or are we doing something wrong?

Thanks in advance

In _state.js we have seen that available events are
return {
onItemSelectedChanged : itemSelected,
onCurrentItemChanging : currentItem1,
onCurrentItemChanged : currentItem2,
onSelectedItemsChanging : selectedItems1,
onSelectedItemsChanged : selectedItems2
};

onCurrentItemChanging only fires once and returns the value of item you have clicked on. This works for what we need right now.

onCurrentItemChanged returns the same value.

try a timeout, it helped me in a similar situation

RB.onItemSelectedChanged = function()
{
setTimeout(function(){
alert(RB.getSelectedItems());
}
}

This is not a bug - onItemSelectedChanged fires for two items, for the previously selected item (from true to false) and for the new selection (from false to true).
