If there is any user in the workgroup and a client got logged saw the group as offline (ok)
But if somebody enters in the workgroup the client receives the available presence but does not show it as available.

The user receives the presence notification:
<presence to="fran1@fran" from="demo@workgroup.fran">
<workgroup xmlns="http://jivesoftware.com/protocol/workgroup">
<lastModified>20070417T23:37:24</lastModified>
</workgroup>
</presence>
