Socket.io server can't broadcast to room

Question

io.on("connection", function(socket){ 
    ...
    socket.on("join", function(id){
        socket.join(room);
        socket.broadcast.to(room).emit("joined", ...);
        ...
    });
    ...
});

socket.broadcast.to(room).emit("joined", ...); haven't any effect it doesn't emit to the room the event

i've already tried to use:
socket.to(room).emit("joined", ...)
socket.in(room).emit("joined", ...) io.sockets.in(room).emit("joined", ...);
io.to(room).emit("joined", ...);
io.in(room).emit("joined", ...);

i'm using socket.io server v1.3.7

any solution?

I've searched on github and nobody knows the origin of this problem..
Probably is a systematic problem of socket.io.
