We are doing the "annotation based approach" described in this link
(https://cwiki.apache.org/WICKET/spring.html). At least, we think we are.
We get:

I thought this might be because that particular service is in the parent
page object and annotated there as well, but I moved it to the child class
and saw no change in behavior. It is a hibernate service and is annotated
in the page like so:
@SpringBean(name="LogTransService")
private LogTransService userTransService;
The exception happens when I go to the page, do a few things (which involve
submitting and redisplaying the page), and then hit the browser back button.
This, as I understand it, causes wicket to deserialize the page from memory.
But shouldn't it see the @SpringBean and re-inject a new service?
Out app object does this:
addComponentInstantiationListener(new SpringComponentInjector(this,
ctx, true));
Ideas?
