For example of how you could validate a form given multiple form fields take a
look at how EqualInputValidator is implemented.
You would have to keep references to the form fields that are related and
return them as an array via IFormValidator. getDependentFormComponents() of
your own IFormValidator implementation. Then you can add as many of those you
want to your form.
Wicket form processing:
------- ---------- --------- ---------- --------
------------
| Start | -> | required | -> | convert | -> | validate | -> | push | -> |
onSubmit() |
| | | checks | | input | | input | | input | |
|
------- ---------- --------- ---------- --------
------------
| | | |
fail fail fail fail
-----------
| | | | |
onError() |
- - - - - - - - - - - - - - - - - - - - - - - - - - -> |
|
-----------
I recommend reading "Wicket in Action" (http://manning.com/dashorst/) or any
other books listed on Wicket's website (http://wicket.apache.org/learn/books/).

Subject: Re: Validating form components in a refreshing view
Hi Josh,
you're right,
I haven't put any in this example because I am really not sure how I should
accomplish this.
If I choose a FormValidator with the FormComponents textOne and textTwo, I can
just compare the values of one row.
I will extend my example later.
