Sounds good to me

It depends on which tapestry version you are using. Later versions of
tapestry will NOT need flash persistence. Later versions of tapestry do a
forward for validation errors instead of a redirect after post. This avoids
session creation for validation errors.
> And where do I set it's value?
It's probably easiest to lazy init a field in a getter instead of @Property
private ValidationFieldTracker validationTracker;
public ValidationFieldTracker getValidationTracker() {
if (validationTracker = null) {
validationTracker = new ValidationFieldTracker(new
ValidationTrackerImpl());
}
return validationTracker;
}
