Yes. People have asked about that several times, but I've never been
sure of the answer. I wondered if it was because we had to use a certain
number of parameters in the bean tags. But we could do both, yes
to do with the taglibs?

Yes, something like that is definately going to find its way into the

These wouldn't exist as such on the ActionResource interface I
suggested. These are really just shortcuts to the API for the underlying
resources, like
formBeans.addFormBean(formBean);
So, if someone wanted to do them through an ActionResources object, they
could do the same thing
actionResour
I had originally thought we might start posting an ActionResources
object in the request, so it would be there when we started to refactor
the tag extensions, and also for the use of other presentation systems
like Velocity templates. So, for a time, it would really be redundant,
and could just ge
ception and be called by the ActionServlet, and the perform() form
would not be called at all. So, like, deprecate perform() in favor of
execute() (or something), if we can get the controller to gracefully
choose between them. But I'm not sure how that would work ;-)

ValidatorForm in the contrib folder generates *lots* of Javascript.
The html:form tag also generates a Javascript to move the focus, as do
