I have been following the discussion from a distance and to me it seems that all solutions that are proposed are rather 'hackish' and make things more difficult to understand too.
First of all, let's agree that your use case is not a typical one. We shouldn't make core adjustements that would make things easier for 5% but harder for 95% of the cases. Anyway, I think what you want can be done rather elegant now. Like you outlined, you should use Button.defaultFormProcessing = false to begin with. In your onSubmit methods of these buttons, you can manually trigger validation and/ or model updates (e.g. call Form.updateFormComponentModels). The next trick is to use models specifically for your view layer, and once you're done with your wizard style functionality, combine these models into something you really need. You won't loose any input this way. Finally, regarding complex validations... As soon as you need to do validations that are dependent on other model properties etc, it is probably wise to leave the default validation path in Wicket. IValidators are very useful for simple validations that are 1-1 related to components, but if you need to do more complex things, they are probably more in your way than any help. If you want to do complex validations easy, you can do them in onSubmit handler code. If you want it more cleanely solved, you should incorperate the workings in your (intermediate) models (and probably have something like onSubmit calling MyModel.validate() or something). Anyway, I think that when looking whether we can make things easier for more complex use cases, we shouldn't be thinking too much about how we can ease things automagically, but instead focus on flexibility and - maybe more important as not everyone seems to understand to current form processing - clarity of form processing and it's possible interception points.
