How to populate a RosterItemVO from a jid?

I’m working on a Facebook chat app where I am creating a new RosterItemVO via RosterItemVO.get():

var ri:RosterItemVO = RosterItemVO.get( fromEscapedJID.unescaped);

var ri:RosterItemVO = RosterItemVO.get( unescapedJID, true);

When I receive a new RosterItemVO normally via a RosterEvent.USER_PRESENCE_UPDATED event, it is always properly populated with the user’s FB info. Is there a way via XIFF that I can populate this info into my newly created RosterItemVO?

what about just setting RosterItemVO properties?

You should send presence data if you want to change your chat status.
