[TYPO3-english] Extbase + Ajax Form Submit + Validation

[Jan Kornblum]

Dear newsgroup,

a controllers newAction() renders a form. This form will be submitted 
using ajax.

Without having any validation errors, the controllers createAction() 
returns a json_encode($status). So far all fine.

But when the form is submitted and there *are* validation errors, 
extbase calls the newAction() again and there is no possibility to just 
get a json_encoded($status) returned (As the *first* call to 
newAction() *should* return the form-markup).

I just want to get the validation errors returned when the newAction() 
is beeing called after a failed createAction().

Is there any possibility to do so?

Kind regards, Jan
