Ohh don't worry. I'm talking about post-alpha-7. We can leave it like it
is now for this release. I'm just trying to keep the framework as simple
as possible. Hmm maybe we'd need how it works in other - non web -
frameworks.

Hey Leonardo,
Sorry I didn't respond earlier. It's been a busy day. The ultimate
constraints wer're working under for this is:
-) Don't want to have actual javascript code embedded on the component
in questions "onChange" etc attributes because they don't actually
fire off valid javascript events. Valid javascript events are needed
for my workaround with Forms and the validation framework. It's sort
of like the enhancement workers in that it's not an ideal solution,
but sort of good enough for now. It's also limiting in that only one
event can be bound to the "onchange" parameter of the component.
-) Using on<whatever> also presents problems because we can't
effectively type off of the attribute name, or at least it will get
very messy very fast. Which events do we "look" for in the attribute?
I can see inefficient if blocks checking tons of values already. :(
The implementation problems are solvable, I just don't see a
reasonable way of doing it currently without code modifications to
tapestry.
Since all of the form stuff already has built-in cool dhtml validation
effects on the client side, it is my hope that this feature won't be
used by as many people as the others?
People are already used to things like listeners/actions being
attributes in tapestry. I think if we make it look and feel very close
to that concept it will be equally as familiar as "onchange" will be.
At least I hope so.
I'm not poo poo-ing the idea, I just don't see a better alternative
that can be completed in a reasonable amount of time for the alpha-7
release. Maybe there is one? I would rather spend more time on fixing
all of these other little things and let this eyesore remain (with the
proposed changes of course) for now at least, hoping to spend more
quality design thoughts on the next alpha-8 release which should
hopefully introduce a couple new very slight changes into tapestry
that will make things a lot easier?
