Can't get room information (dataform) for MUC room

Hi,

I have a User A who creates a default MUC room on Openfire, i.e. "no password", "not persistent", "not public".

However, I create the room with a room name, i.e. I set the field "muc#roomconfig_roomname" of the configuration to a value "My Testroom".

However, when I do the discovery info to the room, I don't get the DataForm with the configured values in the response.

I only get one feature: <featurevar='http://jabber.org/protocol/muc'/>

Any ideas?
