Problem with MultiUserChat.getJoinRooms

Hi everyone..

I have a weird case in getJoinRooms syntaks;

in case :

if i login as User ABC and join room A then i call methode  joinedRooms = MultiUserChat.getJoinedRooms(mConnection,"ABC@servername"); ;

it give me 0 size of joined Rooms, but. when i call methode joinedRooms to getting another user it works fine.

is that methode just can return join rooms that not the user sign in?
