> Key: WICKET-2258
> URL: https://issues.apache.org/jira/browse/WICKET-2258
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Environment: Wicket 1.3.4, Wicket 1.4rc2
> Reporter: Pablo Abad
> Fix For: 1.4-RC7

>
> We are developing a system where some complex validations are handled by
> the domain objects.
> This means that setting some properties may raise exceptions. While we are
> able to catch these exceptions and convert them into meaningful error
> messages that get into the feedbackpanel, this only happens when updating the
> model, right after calling valid() on the form components, effectively
> discarding the values kept in the components.
> Our solution would be to alter the form processing so that:
> + Form validators are invoked
> + If none fails, model is updated
> + if the update doesn't fail, components are marked as valid
> Since this would change the actual form processing cycle, we do not expect
> Wicket to provide this behavior out of the box, but when we attempted to
> subclass Form, and override process() we found out that methods callOnError()
> and persistFormComponentData() called in the implementation of that method
> are private. We need them to be at least protected so that we can rewrite the
> onProcess to suit our needs
