I ran into the same issue, not from upgrading, just starting from scratch.
I resolved the issue by:
1. Making my action implement ModelDriven
2. passing appendPrefix=false to visitorfieldvalidator
For example, my action is
MemberAction implements ModelDriven<Member> {
public Member getModel() {
return member;
}
...
@VisitorFieldValidator(appendPrefix=false, message="")
public Member getMember() {
return member;
}
}
then inside Member.java I have all my validation annotations and it
works fine.
Good luck!

Thanks Gus, you are correct that is the same exact case. I still have
not found a work around other then passing an actually message with:
@VisitorFieldValidator(message = "Please ")
What worked with 2.0.x now does not:
@VisitorFieldValidator(message = "")
Any other suggestions guys? Since Gus and I are the only ones seem to
have this problem, I am wondering if anyone upgraded and was able to
use VisitorFieldValidator without passing a message and without
getting an error?
Thanks, Oleg

Hi,
I had the same problem. I didn't manage to fix the problem as I ran out of time
but I can tell you what I discovered which may help you.
I found passing in a message e.g. @VisitorFieldValidator(message="Visitor")
stopped the exception you described from being thrown. However passing in a message to
the VisitorFieldValidator is not very useful but it was just something I tried to try and
narrow down the problem. When I removed the VisitorFieldValidator the exception is still
thrown as was the case for you.
I realise this doesn't help you much but its as far as I got when looking at
the problem.
If you have any luck in fixing the problem I would be interested in hearing how
you did it.
Cheers
Gus.

Subject: Problem moving from 2.0.14 to 2.1.6
I am trying to upgrade to 2.1.6 and getting an error on Validation
that I am having problems isolating. I followed migration guide at
http://cwiki.apache.org/S2WIKI/troubleshooting-guide-migrating-from-struts-20x-to-21x.html
and didn't actually have to change that much since application is in
very beginning stages.
The error I am getting is attached below and I am getting it from
@VisitorFieldValidator, however even when I remove all validation
annotations from that visitor object, the error still pops up, kind of
lost here, any suggestions?
