Whiteboard history

Hi,

If two users are working on a whiteboard session they can both see each others work without any problems whatsoever. But, if a third user later joins that whiteboard session, s/he will only see what is being worked on from the moment s/he joined in. That is, s/he will not be able to see what the other two users have been working on prior to s/he joining in.

Is this an intended behaviour when whiteboarding? Would it be possible for a new user to join a whiteboard session and see the content which already exists within it? If so, is it a case of re-configuring Coccinella or the XMPP server which is hosting the whiteboard session?

Our setup is:

Openfire server on Ubuntu linux server.
Coccinella 0.9.18 on Windows XP clients.

Thanks in advance for any help on this!

Regards,
PM.
