Have compared with few other clients. Yes, it seems that Gaim is showing it in its own way Though all this stuff with ID, Name of room is a little confusing.
Room ID in Wildfire is a before @ part of room’‘s JID. So if Room ID is say “chatroom” so the JID would be firstname.lastname@example.org . And the Name would be Room Name in Wildfire Admin Console. Now it’'s more clear when @chatservice.server line was added near Room ID input field. Because when i just started using Wildfire/XMPP i thought this is some ID just for server admin purposes.
Some interesting thing. Spark in Room Info window is refering to a email@example.com as a Room Name Though it should be called Room ID or JID.
Dont know what are the requirements of XMPP about this stuff. But i think this should be tested with some other jabber server and then reported to Gaim developers.
