Are you returning a ForwardResolution to another action, or directly to a JSP?
Field repopulation with the default PopulationStrategy should get the values
from request params. If you are not getting them back, then something is
messing with them… A redirect, a changed param name… Another thing to check,
ValidationMethods happen after @Validate annotations, so they’re not been
called if you are using @Validate(“required=true”)…
I’ve just made a little test app, and works ok (I’ve stripped some plumbing
code, though):
index.jsp
<s:form beanclass="my.action.PostAction">
a: <s:text name="a" /> <s:errors field="a" /> <br/>
b: <s:text name="b" /> <s:errors field="b" /> <br/>
<s:submit name="execute">Send</s:submit>
</s:form>
IndexAction
public class IndexAction implements ActionBean {
@DefaultHandler
public Resolution execute() {
return new ForwardResolution("/WEB-INF/jsp/index.jsp");
}
}
PostAction
public class PostAction implements ActionBean, ValidationErrorHandler {
@Validate(required=true)
private String a;
@Validate(required=true)
private String b;
@DefaultHandler
public Resolution execute() {
System.out.println(a + “ “ + b);
return new RedirectResolution(IndexAction.class);
}
@Override
public Resolution handleValidationErrors(ValidationErrors errors) throws
Exception {
return new ForwardResolution(IndexAction.class);
}
}
Hope it helps!

Just a plain JSP with a stripes-form tag that refers to an action bean.

Both. I have some validation annotations and also implement
ValidationErrorHandler. I also have a method marked
@ValidationMethod(when=ValidationState.ALWAYS) for the event in question.

The resolution returned is of class ForwardResolution.
I could send some code, but it's really rather huge and has quite a few
dependencies.

Except that you example only has one field, which is not enough to exhibit the
problem where one field is valid and another is not.
I'll try to dig into a TRACE log to see if any hint is to be found there.
