Re: Multipage forms and validation
When the time comes, David's Validation servlet would get my vote. Unfortunately, we need to get 1.0 out the door before voting on anything like this. Beta 3 is counting down now, so we only talking a couple of weeks now. In any event, what features Struts, or any Jakarta product, will offer in any timeframe, will always depend on what people contribute. No one here can say hey you, go implement this feature. What gets implemented depends on what people choose to contribute, and David has stepped forward with a very fine contribution. One of things that make it a fine contribution is that the Validator servlet snaps right into the framework, without altering anything else. So you're free to use it, or not to use it, or to use something else. Which is as Struts-esque as you can get ;-) So I'd say use it .. I do!

I'm just wondering whether to plough on with what we've got or wait for what might be coming in Struts. Niall

RE: Multipage forms and validation
It hasn't been discussed by the other volunteers and Struts users/developers exactly what features the client/standard validations should have. I'll send an e-mail to get the discussion started.

Re: Multipage forms and validation
I've done some work on a validation framework for Struts that is based on defining rules in an xml file. Right now it depends on associating a field with a page and setting a variable in the JSP page to set what page you are on.
