Why? Did you run my test?
Note, onError calls target.addComponent(form) and the values are not lost. From
my understanding (as the component user), the raw values should be maintained
when rendering the component, but not on subsequent requests.
> When a form is not valid, the textfields become with "raw input" and can't
> change its model on subsequent requests
