Why not to use request attributes and place a HashMap with error messages
there?
My approach is this:
1. Form validator action validates posted data, creates some object (some
XML 'instance data' if it's not present yet) and places error messages (or
only error codes) there. Then that 'instance data' is added to the request
attributes.
2. A form navigator action checks the result (some error flag in the
objectModel) and depending on the result returns a 'nextpage' param.
3. Every form is processed by a FormTransformer which replaces special
output tags (e.g.: <output ref="errors/error[@id='password']'" />) by the
error message from the 'instance data' according to the 'ref' attribute.
4. ??? Who must remove/clean instance data?
(Some ideas was taken from the W3C XForm Specification)
