Custom Validation implementation

[wicket_new_user <mu...@gmail.com>]

Hi all, 

Is there a way to do the validation for all the fields in one area without
using onValidate method.

I mean, the form data will be converted to domain data, do the validation
and throw error message if any found before persisting to the database?

Thank You

Hi,

Wicket IValidator is used before converting the string sent by the browser
to a domain object. This way if there is a validation error the old (and
correct) value is still in use.
You can achieve your approach by making your validation in #onSubmit().
Here you can work with the domain object but if there is a validation error
then you need to restore the form components' models to the previous
(correct) ones, not only skip the write to the DB.
