Re: Form field (value) does not update after validation error
Thanks, this works, at least when calling this on the entire form object.
Still I think this is a bit strange since it is a new request, after
pressing the link. By that time the error message is also gone, while
the form stays with these old values.

is an 'edit' button which will set that specific cheese object as a
the current model object in the form, which results in the name and
kiloPrice field in the form being filled with the values of the

If then, for some reason the validation of a form post fails (the
price is too high for this Gouda), and I (as an end user) decide to
skip editing this Gouda cheese and press the edit button of the
Cheddar cheese, the form will not be updated with the name and price
of the Cheddar. The values of the Gouda remain. Even though the
current object in the model was updated to Cheddar.
When I now press the submit button again (after putting a correct
price in the field), the Cheddar object is updated with the values of
the Gouda (which were still in the formfields).
I can make a bigger example like this if needed.

Re: Form field (value) does not update after validation error
don't know if i totally understood the setting of your example, but
your edit button shouldn't submit/post the form, eg. just use a Link
attached to an input type=button tag instead of a Button.
