room.getJoinedMembers always returns zero room members

Nobody has claimed this yet.

I just need to be able to query room members at an arbitrary time (rather than via an event.)

matrixClient.joinRoom(roomId).done(function(room) {
console.log("joined room");
var memberList = room.getJoinedMembers();
console.log("there are %s people in the room.", memberList.length);
for (var i = 0; i < memberList.length; i++) {
console.log(
"(%s) %s",
memberList[i].membership,
memberList[i].name
);
}
});

Always returns zero people in the room, when I know there are several. I have also tried room.currentState.getMembers() and getLiveTimeline().getState('b').getMembers(), same problem.

The only way I can successfully get a list of room members is using the sample code, for when room state changes.

Am I doing this wrong?

tested on 0.8.5 and 0.9.0.

The report names room.getJoinedMembers(), room.currentState.getMembers(), and getLiveTimeline().getState('b').getMembers(); start by reproducing the behavior after joinRoom(roomId) on the referenced SDK versions. Done means the appropriate member query returns existing joined members, not only updates received from later state changes.
