No, Wicket is not trying to serialize your DAO. The exception occurs in the
action phase of the request handling. It looks like you've passed an object
to MongoDB which has a reference to the @Injected DAO, or at least to the
component that has the DAO. It's this MongoDB DefaultDBEncoder.writeObject
thing that's serializing/encoding something it shouldn't.
If it's not clear by inspection how the object being passed to save() holds
a reference (e.g. by being an inner class) then set a breakpoint and the
debugger should point to the offending reference.
