>             Project: Tapestry 5
>          Issue Type: Bug
>          Components: tapestry-core
>    Affects Versions: 5.4
>            Reporter: Geoff Callender

> Found this bug in 5.4-beta-22. I've confirmed that the bug was not present in 5.4-beta-6.
> When an error is recorded with Form.recordError(Field field, String errorMessage) or ValidationTracker.recordError(Field field, String errorMessage) it normally is shown in the UI by decorating the field in error and displaying the errorMessage below it.
> However, when the request is AJAX, the field is no longer being decorated and the errorMessage isn't shown with it. I have verified that the client knows about the error, because <t:errors globalOnly="false"/> will show it.
> Comparing the HTTP responses of beta-22 with beta-6, I see that beta-6 has an extra entry in the inits, like this:
> ["t5/core/fields:showValidationError", "firstName_8cf3108fe0ece9", "First Name must not be Acme."]
