RE: [flexcoders] F2.0 final - Possbile bug with PopUpButton and PopUpMenuButton

I've also encountered this bug (event dispatched twice).

Here is a workaround :

private function itemClickHandler(event:MenuEvent):void {

if (event.index != -1) { // Workaround to ignore the second event

...

}

Objet : [flexcoders] F2.0 final - Possbile bug with PopUpButton and PopUpMenuButton

4 days after the release I come to update my Flex Application from Beta 3 to Final and the 2 main components I used seem to be bugged. not very good at explaining things to bare with me please :p

PopUpButton

    - Every time I select an item... the "itemClick" event gets dispatched twice. it just pops with with 2 Alert dialogs every time I select an item

PopUpMenButton

    - When I put my mouse over an item for the first time.... works fine... but soon as I hover over another menu item in the main level... the menu closes automatically and also if I Hover over an item that is a sub menu.... I can keep going in and in until there are no more children... or I could just go in once... and then soon as I hover over another item... again the menu just closes. Both times this is without click on any items in the menu

I've posted the code below

Flex code being:

<?xml version="1.0" encoding="utf-8"?>

            private var i:uint = 0;

            // Initialize the Menu control, and specify it as the pop up object
            // of the PopUpButton control.
            private function initMenu():void {
                myMenu = new Menu();
                var dp:Object = [{label: "New Folder"}, {label: "Sent Items"}, {label: "Inbox"}];
                myMenu.dataProvider = dp;
                myMenu.selectedIndex = 0;
                myMenu.addEventListener("itemClick", itemClickHandler);
                popB.popUp = myMenu;
                popB.label = "Put in: " + myMenu.dataProvider[myMenu.selectedIndex].label;
            }

            // Define the event listener for the Menu control's itemClick event.
            private function itemClickHandler(event:MenuEvent):void {
                var label:String = event.item.label;
                popTypeB.text=String("Moved to " + label);
                popB.label = "Put in: " + label;
                popB.close ();
                myMenu.selectedIndex = event.index;

                Alert.show('menu popup number ' + ++i);

Flex code end;

Is it possible these are bugs? I've tested this with flash player 9.0.15.0 ( with debug ) and 9.0.16.0 ( without debug )
