I am using Jitsi version 1.0-beta1-nightly.build.3565.
I connect to an ejabber server (latest binary download) which is configured
to allow users to create their own chat rooms.
A jitsi user connected to above jabber server, creates a chat room. But it
can only see itself in the "list of users in the chat room" on the right
side of the screen. I had two or three users who joined that room but it
can't see that.
This problem is only experienced by the user who created the chat room. A
work around is to quite jitsi and relogin into the chat room. It works after
1 or sometimes 2 attempts.
I have got a setup here so can provide you feedback.
