Question

I have this class

@HasNose
@HasMouth
public class Person {

    String fieldA;
    String fieldB;
    // getters and setters

}

Now the custom annotations validator look something like this

// validator of @HasNose
@Override
public boolean isValid(Object object, 
                        ConstraintValidatorContext context) {

    // some tests that determine there is an error
    context.disableDefaultConstraintViolation();
            context.buildConstraintViolationWithTemplate("Some message")
            .addNode("fieldA")
            .addConstraintViolation();

}

and

// validator of @HasMouth
@Override
public boolean isValid(Object object, 
                        ConstraintValidatorContext context) {

    // some tests that determine there is an error
    context.disableDefaultConstraintViolation();
            context.buildConstraintViolationWithTemplate("Some message")
            .addNode("fieldB")
            .addConstraintViolation();

}

Running this produces the exception:

java.lang.IllegalStateException: JSR-303 validated property 'fieldA.fieldB' does not have a corresponding accessor for Spring data binding - check your DataBinder's configuration (bean property versus direct field access)

For some reason “ConstraintValidatorContext” is concatenating both fields. Debugging shows that the attribute “propertyPath” comes already filled out with “fieldA”.
I thought it should be at the root level per constraint validator doesn’t it?

I found the solution for my own problem, I was using hibernate-validator-4.2.0.BETA2. Switching to hibernate-validator-4.2.0.FINAL solved the issue.

Lesson to learn: keep your libs updated…
