[flexcoders] PopupButton bug

Wed, 01 Mar 2006 15:25:12 -0800

I looked around for the proper way to report this but could find it.  The code below is from the PopUpButton livedoc, the only change I made is that I commented out the line that changes the label of the PopupButton instance after a menu item is selected.  Doing this causes the menu to not disappear after selecting an item.  If you run this code, just click the "Put in: Inbox" button, and select one of the menu items.  The menu doesn't hide.  If you uncomment the line that changes the label and reload it, the menu will hide as expected.

            // of the PopUpButton control.
            private function initMenu():void {
                myMenu = new Menu();

                    {label: "Inbox"}];       
                myMenu.dataProvider = dp;
                myMenu.selectedIndex = 0;      
                myMenu.addEventListener("change", changeHandler);
                popB.popUpObject = myMenu;
                popB.label = "Put in: " +
            myMenu.getMenuItemAt(myMenu.selectedIndex).getProperty("label");
            }

            // Define the event listener for the Menu control's change event.
