[T4] ValidationDelegate to edit attributes?
I'm trying to develop a customized ValidationDelegate that add a
class to fields with an error. It works if the field doesn't already
have a class attribute. What I want to do is add the class name to
the existing attribute. Just adding one yields two class=""
attributes, which doesn't seem to render properly. (The second one is
completely ignored in some browsers.)
How can this be done? This is using Tapestry 4.0.2.

Alas, I decided to use 4.0.x due to the instability of 4.1 for this
project. I guess for now, I'll just print the label in red and
nothing else. I can't do the "**" after the field since that
completely messes up the formatting (everything being placed rather
precisely.)
I could probably do a writePrefix to insert a span with the class.

If using tap 4.1.2 (I know, sorry ) I think it just works as expected - but
there's also some new api calls for handling stuff like this - ie
appendAttribute() / getAttribute() / etc...
