@VisitorFieldValidator message formatting question.
I'm trying to use the VistorFieldValidator via annotation. The validator is
being called ok, but using @VisitorFieldValidator() all the error messages
are prefixed with the word "null". If I use
@VisitorFieldValidator(appendPrefix=false) then I don't get any error
messages at all.
Why am I getting "null" prepended to the message string and how do I stop
it?
Regards

Forget what I told you about fieldName, try simply to change value of messge
inside visitor annotation. Setting append prefix to true tells struts to
prepend message to error fileds.

Hi Maurizo,
I've upgraded to 2.2.1 and the behaviour has changed slightly, but still
doesn't tie in with my expectations or yours (if I've understood your
explanation). Firstly specifying the fieldName="My Field Name" still makes
no difference whether I include or exclude it. Secondly, specifying
appendPrefix="false" with or without message="My Message" still produces no
error messages at all in both cases.
Where the difference occurs is now @VisitorFieldValidator(fieldName = "YOUR
FIELD NAME", appendPrefix = true, message = "") now outputs <Message
generated by error condition> instead of <null><Message generated by error
condition>
Regards

At first glance everything would seems correctly configured (except
for that unnecessary RequiredFieldValidator).
Did you try it in a more recent version (like 2.2.1)?

My guess is that there is something wrong in your configuration.
Could you post your annotated class?

This doesn't work as I would expect;
@VisitorFieldValidator(fieldName = "YOUR FIELD NAME", appendPrefix = true,
message = "YOUR MESSAGE") outputs <Your Message><Message generated by the
error condition>
@VisitorFieldValidator(fieldName = "YOUR FIELD NAME", appendPrefix = true,
message = " ")
outputs <null><Message generated by the error condition>
@VisitorFieldValidator(fieldName = "YOUR FIELD NAME", appendPrefix = false,
message = " ") or
@VisitorFieldValidator(fieldName = "YOUR FIELD NAME", appendPrefix = false,
message = "YOUR MESSAGE ")
outputs no error message at all.
It doesn't make any difference whether I include the fieldName="YOUR FIELD
NAME" or not, the string "YOUR FIELD NAME" never appears in the ouput.
I'm using 2.0.18 if that's of any relevance. I would have expected that
specifying either appendPrefix=false or appendPrefix=true, message=" " to
display only the generated error message. What is the fieldName attribute
for?

Ok,
try this
@VisitorFieldValidator(fieldName = "YOUR FIELD NAME", appendPrefix =
true, message = "YOUR MESSAGE")
Struts should use Field Name like a prefix for every invalid element
inside the annotated object.

I've read the documentation several times. I didn't understand that
paragraph then, and I still don't
understand what it means now :(
Any pointers to an example?

According with documentation appendPrefix "Determines whether the field name
of this field validator should be prepended to the field name of the visited
field to determine the full field name when an error occurs"
this link should be useful
