PROBLEM with RoomList

[slayerzphb]

In my project, connect is ok...
later i use
getRoomList();
onRoomListUpdate = function (roomList)
and then join in a room right?
its ok...
onJoinRoom = function (roomObj)
gotoAndStop("chat");
"
but the problem is:
when is in "chat"
NOT LIST THE ROOMS!

i tried the code:
....onRoomListUpdate = function(roomList:Object)
{
trace("test for see");
roomList_lb.removeAll()

for (var i:String in roomList)
{
trace("test");
var room = roomList
roomList_lb.addItem(room.getName() + " (" + room.getUserCount() + ")", room.getId())
}
roomList_lb.sortItemsBy("label", "ASC")
}


i make this project based in many parts based in example of PIXEL GAME.
i don't know, i tried many things but in CHAT NOT LIST ROOM!
nothing happen!

the original code of project:
mylist = function (roomList:Object)
{
trace("testtttttttttttttttttttttttttttttttttttttttt");
for (var i:String in roomList)
{
trace("test okkkkkkkkkkk");
if (roomList != "")
{
......................................

in first, NOTHING HAPPENS!
in second( mylist = function (roomList:Object) )
return me trace("testtttttttttttttttttttttttttttttttttttttttt");
but...
