Presence Type Invisible

i get a warning at the log-console for the invisible status:

|2008.04.23 09:27:42 Invalid presence type
java.lang.IllegalArgumentException: No enum const class org.xmpp.packet.Presence$Type.invisible …|

Some helpfull ideas, because im not sure if the invisible status is working?

thanks

There are several protocols for “invisibility” out there. Openfire does not support any of them, it has its own protocol, implemented with 3.5.0. (more details)

Thats the disadvantage of an open protocol, is possible that there are serveral mutually exclusive protocols for the same thing.
