That's how I'm doing the validation right now, but I was wondering if that functionalities (the error list, etc) aren't already implemented in Wonder. They seem to be in ERXValidationFactory but I really don't quite understand how to use it.
You don't really have to use it. If you really want more sophisticated validation there is the Validity framework. I had no need to use it, as the normal validation with the Wonder extensions gives me enough features.
I didn't have to change anything for validation when integrating Wonder in applications.
Actually, I just use the "normal" WebObjects validation with implementing the correct methods, catching the exceptions and so on.
If you don't want to implement that stuff all the time, create a generic edit page, implement the method there and handle all problems there. That's how I do it.
Chuck's book seems to be the WO bible. :) And it's a great book actually. I'll try to find out more about the validation methods there.
As I said, create a superclass with the methods you need for the validation and you don't have to worry about it anymore - only catch some special cases in the subclass implementations.
Looking at how ERDirectToWeb - ERD2WInspectPage and ERD2WPage handles that is a good thing!
