XML Forms again
Hello,
another issue concerning XML-forms:
In the action for the form processing, the method
filterRequestParameters(..) should be used for validation that
exceeds Schematron validation.
Could someone please provide an example, or give an explanation how to
use this method.
I don´t understand if I am supposed to do the validation within this
method (but why then: "return false if the
request parameter should not be filtered....), or if something happens
according to the value returned?
What follows is then how to get error messages back?
Still I am wondering, if I can use the bean used for the model, outside
of my FormAction or if it is only
possible to use it in this action.
Thanks again for any help!

You will use this method to tell XMLForm to *ignore* certain request
parameters when going through the automatic population and validation.
In most cases you don't need to override this method.
What kind of validation do you need to do which a Schematron schema can't
provide.
You can do additional custom validation in your perform() method.

A form and its model are stored in the servlet session or request. You can
get it with Form.lookup( YourFormId )
The XMLFormTransformer accesses the same Form as the action.
