I haven't found anything that does a good job covering Wicket 1.3 and I
haven't looked at books which cover older versions. There is "Enjoying Web
Development With Wicket" which is available as an ebook, but it is really a
series of how-to's - fairly superficial, with no real discussion of how the
guts of the thing work or best practices.
Wicket in Action is definitely a long way from finished but the available
chapters do provide a good grounding in fundamental concepts like models and
page layout/navigation.
