> The changes introduced into r898476 to address TAP5-979 has introduced the new ValidationTrackerWrapper.
> This seems to cause a regression in the way form validation is processed.
> The old (and wanted) way is to have onValidate to check for form-wide validations and store into the form (form.recordErorr) any found violation. Then if there are violations (errors recorded) the form fire the onFailure events otherwise go to onSuccess.
> With this changes the event path goes always from validate to success events, the failure event is never fired.
> The only possible workaround is to have the onFailure event handler method to return an object (typically this) and never be of type void.
