Apr 09, 2010 Apr 09, 2010

After clicking to radio buttons i see next error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
     at fl.controls::RadioButton/drawFocus()
     at fl.core::UIComponent/focusInHandler()

i used next code:

import fl.controls.RadioButtonGroup

public class CoinToss extends MovieClip 
     {
          var radioGroup1:RadioButtonGroup=new RadioButtonGroup("Coin Loss");

//constructor
          public function CoinToss()
          {
               //changing existing cursor to our custom
               Mouse.hide();
               addEventListener(Event.ENTER_FRAME, myCursor);
               my_cursor.mouseEnabled = false;
               
               gameMenu();
          }

public function gameMenu():void
          {
               gotoAndStop('homeScreen');
               
               homeBtn.addEventListener(MouseEvent.CLICK, homeScreen);
               playGameBtn.addEventListener(MouseEvent.CLICK, gameScreen);

public function gameScreen(event:MouseEvent):void
          {
               startGame();
          }

public function chooseAnswersGroup():void 
          {
               gameScreen_mc.eagle_rb.group = radioGroup1;
               gameScreen_mc.tails_rb.group = radioGroup1;
          }
          
          function startGame():void 
          {
               gotoAndStop('gameScreen');
               var gameScreen:Tween = new Tween(gameScreen_mc, "x", Elastic.easeOut, -200, 10, 2, true);
               chooseAnswersGroup();
                        gameScreen_mc.eagle_rb.selected = true;

Here you go:-

1) It is possible that you have change/delete any component related file in library. So when u replace it you got it right.

2) It's a tab focus rect of flash player. Possible you have pressed tab that's why u can see it on radio button.
