That must be the point, of course.
But why are form fields implemented in different ways?
There are fields like ie TextField, that record their input value
into the trackings, even if there was no error.
On the other side, PropertySelection or Checkbox, record only errors
into the trackings.
This is an inconsistent behaviour for elements, that are - in my
opinion - supposed to work similar.
It would be nice to know, in which direction the development of
Tapestry is heading. Will there be a "default behaviour" some time?

P.S. I've extended all form elements that I needed and changed some
methods, so that all form elements always register with
ValidationDelegate.

My guess is that you won't need those fields unless you have some
error to show and you want to tell the user which field was wrong.
If this is the idea for the most common use of field validation,
the consequence is that you don't want to take note of unused data.

Thanks for the hints!
I've implemented both classes and added the following code:
rotected void rewindFormComponent(IMarkupWriter writer,
IRequestCycle cycle)
{
[...]
IValidationDelegate delegate = getForm().getDelegate();
if(delegate != null)
{
delegate.recordFieldInputValue(value);
}
[...]
Now every input value is also stored in the FieldTrackings and
every validated FormField
is on the list, wether it stores an error or not.
Is there a reason why this is not the "normal" behaviour of these
standard components?
