This is probably a question for the user group, but I thought I might post
it here first.  In putting together an application based on Wicket I've
noticed the following:

1.  Load a form full of Ajax links and features, and even an
AjaxSubmitButton / Link.  But it's not easy to have the AjaxFormSubmit
behavior invoked by <CR>.  In many cases, the traditional, non-ajax submit
behavior is triggered.  What is needed appears to be something at the body
level to handle keydown events.  One can do this in a variety of ways, but I
can't help but think that something more user-friendly, such as [class
AjaxForm extends Form] would be helpful to the user community at large.

2.  While we're at it, if we're trapping events at a high level like <body>,
why not put together a javascript framework, in the form of a map, where
keyCodes from keydown events are mapped to AjaxEventBehavior fn's, and the
functions executed.  This would enable ajax based HOT KEYS for an
application.  Trapping events at <body> would also ensure that <ESC>
triggered the ModalWindow's cancel behavior.  This would mean a small change
in the IBehavior API, or perhaps higher up, since only Ajax*Behaviors appear
to make contributions to the DOM.  Most other behaviors exist to customize
tag attributes, and wouldn't participate in such a scheme.

3.  In order to do such trickery, I've noticed that what's rendered up by
AjaxEventBehavior.getEventHandler() isn't working when offered to
javascript's eval.  There's additional decoration that might be getting in
the way (I'm testing this now), or perhaps eval isn't compatible with the
framework provided by wicket-ajax.js.  Either way, what is really needed is
an API that offers up javascript and not strings from Behaviors.  Vaynberg
said that this is on the way.

How soon, and who would be doing the work?  If possible, this is something
in which I'd like to participate, the sooner the better.

I know that these items of functionality may not be the priority to the
larger Wicket developer community than they are to me, but to move forward
with Wicket as our preferred presentation framework, these items (especially
trapping <CR> on forms and executing the default button's ajax form submit
behavior fn) have to be in place.

Since there are many ways to do these things, I'm interested in hearing the
solutions of others, or if I can be some assistance in this matter.
