I don't think that anybody has tried this yet. The AjaxEventSubmit
component is intented (for now) to submit the whole form and call a
listener. Hence the "Submit" suffix. This is important in many cases
where people need to change the old "combo-box changed -> refresh"
pattern that plage a lot of web apps. So it works mostly like a submit
button.
(I'm not sure if in a regular Submit button the form's listener is
called too. If that's not the case then AjaxEventSubmit shouldn't do it.
But I think is the case indeed).
You might want to take a look to how Autocomplete is working. Maybe it
would shed some light on your purposes.

Hi guys. Looks like this is going in a cool direction. However, I’m a
little confused about the version in alpha-7.
I’m building a form with a TextArea that kindof works like an
AutoCompleter. I put the TextArea inside an AjaxForm, and I’ve
attached an AjaxEventSubmit to the onkeyup event of the TextArea.
The server-side listener needs the input of the TextArea to generate
suggestions. (BTW: I can’t use an AutoCompleter because the
suggestions shouldn’t appear in a pull down, they need to appear in
some other part of the page.)
So the AjaxEventSubmit gives me two choices for attaching a listener.
I can use the “action” parameter which causes tacos to fire the
specified listener right before firing the form’s listener. Or I can
use the “listener” parameter which causes tacos to fire the listener
method when the AjaxEventSubmit component rewinds.
In the first case, my form’s listener fires too. That’s not the
behavior I want. I only want the AjaxEventSubmit listener to fire in
this case.
In the second case, the listener **must** fire before the TextArea
rewinds because I **must** place the AjaxEventSubmit component before
the form elements which trigger it. So in this case, my listener can’t
get the data it needs.
I don’t quite know what to do here. Am I using the AjaxEventSubmit
component for an unintended purpose? I notice that the AjaxForm in the
demo doesn’t have a “listener” parameter or a LinkSubmit or anything.
Perhaps nobody has tried this yet?
Thanks for your help!
