When I set up presence (this is based on examples from the book), I create a Net::Jabber::Presence object, fill it appropriately, and pass it to $connection->Send() (not PresenceSend). It works for me.

It's a 'wrong type of argument' problem, but not with Send(); in this case
it's with the new() method of Net::Jabber::Presence() - called in the
handle_presence() callback in the script. As Piers, and the nj10021.html
article, has already mentioned, what is happening is that Net::Jabber is
now sending two values to the callbacks - the first being a session ID,
the second being the one that we really want to pass to the new() method.
Pre-1.0021, it just sent the latter value.

I haven't found anything yet that affects me in the code examples, but there is always the possibility that something has gone amiss. I suggest you check the Errata page for the book on the O'Reilly website. Also, as you have already pointed out, the Net::Jabber libs are a moving target, as is Jabber itself, to some extent.

Stephen - I try to check the Errata page regularly, but please don't
hesitate to bug me by email (dj.adams at pobox.com) with anything you find
and want to ask about or thwap me over the head about :-)
