lack of search). The theory would be that your dynamically generated
ModelForm instance could apply this validation service to the
model. The
RequestHandler on post-back could determine the ModelForm and
execute any
defined validation service (if technically feasible).
What you could perhaps do is make sure you use services as your
request map events and then create a special request/event that you
can call via ajax that will valid the parameters against the service
definition by serializing the form and telling it what your target
request is. There is a seldom used child element to service ->
attribute called type-validate which can allow you to do custom
field level validation on incoming parameters.
You just need to call modelService.validate(parameters, "IN",
locale) in your special validation request/event and you're done.

What I am getting at here is an ability to model a "validation
service" as part of the ModalForm. How it is implemented (sever-side
vs. ajax callback) would really be secondary. I like the ajax
approach for the validation that you have suggested in the
implementation ... I was just thinking if you were going to add
validation logic to your survey you could expose that through an
extension to the ModelForm (since that is what survey is creating
dynamically) and then we would have an ability that could be leveraged
in a number of spots. This would be versus having a survey validation
service that your survey handler happens to call first before the
async execution service.
