I wouldn't say it's lame, it's just the way it is. No other event
system I know of would ever allow ordering event handlers. In fact,
treating all handlers equally allows an option for executing them in
parallel (even if current Javascript engines don't do that).

First of all, thanks for the well-written wiki page Chris, it's very
informative. I'd think the right way to solve the problem is to use
event propagation as intended. That is, in the case of confirm(), you
should target the element inside of your actionlink - for example:
delete
Then add a handler for the nested element:
Event.observe($('confirmDelete'), 'click', function(event) {if
(!confirm('are you sure to delete this record ?')) event.stop();});
to stop the event from being propagated to the actionlink handler.
You could probably attach the confirm mixin to an Any component
outputting a span. If you put a button inside, it'd be even easier
since you could just do onclick="return confirm(...);". Unfortunately
it's not possible, or at least not trivial, to create a mixin that you
could attach to the parent element but make it listen to a "click"
event of a nested element - and I don't think it would be cool if the
mixing would programmatically modify the parent element (since that's
how I see you could get it done if you really wanted to).

Re: T5 - MarkupWriterListener
Thanks for your reply Thiago. The mixin method would work I guess but what I'm trying to do is remove the 'name' attribute generated by the Form component (because it is not valid in the Strict Doctype). I don't want to add a mixin to every form in my application. Is there any way that I can register this with the framework when the application starts? I.e. get hold of the MarkupWriter so that I can call its setListener method?

Re: ZoneUpdater -> null strings ...
Hi!
I just copied the JumpStart example ... i.e. copied ZoneUpdater.java +
ZoneUpdater.js.
My html is also using jquery in noConflict() mode.
My tml looks like ...
.tml
Currently I have added a "dummy" in my action methods which works.
But it would be nice to sort it out.

Re: ZoneUpdater -> null strings ...
The $N is probably a client encoding of null.
Are you passing a context to the mixin? The provided context seems to be
[null, 'XXX'], where XXX is replaced by your real value on the client.

Re: Help with ZoneUpdate
The Zone raises a JS event when is updated. This is explained in the
Zone documentation:
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Zone.html
"After the client-side content is updated, a client-side event is
fired on the zone's element. The constant Tapestry.ZONE_UPDATED_EVENT
can be used to listen to the event."
You just need to provide a Prototype listener for that event in your page.
