Doesn't work muc.getOccupants() in 4.0.0-rc1

MultiUserChat muc = new MultiUserChat(connection, room);
List occu = muc.getOccupants();

muc has null size of the occupantsMap.

2

MiltiUserChat.java

method “init()”

presenceListener

row 1987:

Presence oldPresence = occupantsMap.put(from, presence);

This code doesn’t assign the values of the occupantsMap.

occupantsMap is not null, but oldPresence after this code is null.

I’m sorry I can’t follow. What exactly is wrong in the packetListener for MUC presence updates? What would be your proposed solution?

4

I’m sorry. It was wrong approval that erorr in “Presence oldPresence = occupantsMap.put(from, presence);”.

I need more time for debug…

In one of the steps of initializations “occupantsMap” is rewriting by null

5

I don’t know why but after reading packet MultiUserChat is recreating that why occupantsMap is empty

6

after row 2034 it went to class PacketMultiplexListener in method “processPacket” . This method starts again “presenceListener”

When it all returns in MultiUserChat class - occupantsMap recreating

7

I’m sorry I can’t still follow. occupantsMap is only cleared if the room is left or the user is kicked. I’m still unable to grasp what you are trying to tell me.

8

it’s easy to check.

just execute “muc.getOccupants()”

Is it works?

I guess this may because you are using new MultiUserChat to get an instance each time, as i made this mistake before. try just new once and reuse this instance afterward.

It might also be related to this issue, which I’ve described here:
