This question might be best directled to isis-users, so I've cc'ed this
reply  there.

fyi, I suggest that you subscribe to that list (mailto:
isis-users-subscribe@incubator.apache.org).  But by all means subscribe to
this list too (mailto:isis-dev-subscribe@incubator.apache.org) if you are
interested in contributing to Isis in the future.

The short answer is: you do need a setter, but must have no public getter
for that injected service.  The fix is simply either to remove that getter,
or to mark it as protected, package or private visibility.

If that doesn't fix things (or you don't have a public getter but even so
are still having the exception), then let us know.
