flex - dropdown following moving calloutbutton -

-

flex actionscript question.

i have calloutbutton moving on screen. when open dropdown (by click) stays @ same position on screen (only arrow moving). not follow calloutbutton's position

i dropdown follow position of calloutbutton when has moved (as when 1 clicks on button again when has moved).

i have tried dispatch mouseevent.click. not work. tried open, close again dropdown actionscript sing closedropdown() , opendropdown(). no change.

thanks

sample code (call init() creationcomplete) :

    creationcomplete="init();"> <fx:declarations>     <!-- place non-visual elements (e.g., services, value objects) here --> </fx:declarations> <fx:script>     <![cdata[         import flash.events.mouseevent;          import mx.events.dropdownevent;          private function init():void {             var minutetimer:timer = new timer(1*1000);             minutetimer.addeventlistener(timerevent.timer, updatecalloutposition);             // starts timer ticking             minutetimer.start();                         }          private function updatecalloutposition(event:event):void {             mybutton.closedropdown();             mybutton.x = this.width * math.random();             mybutton.y = this.height * math.random(); //              mybutton.opendropdown();             mybutton.dispatchevent(new mouseevent(mouseevent.click));         }          protected function mybutton_clickhandler(event:mouseevent):void         {             if (mybutton.ispopup) {                 mybutton.closedropdown();             }             else {                 mybutton.opendropdown();             }         }      ]]> </fx:script> <s:calloutbutton id="mybutton" click="mybutton_clickhandler(event)"> </s:calloutbutton>
