Perhaps the tapestry.linkOnClick(url,id,isJson) will do the trick.
In the url you can put the info you want to send to the server.
Take a look at the timetracker application for a sample of how to use it.

Hello Jesse & Mark,
I am in the same situation as Mark was some time ago, at least I think the
situation is the same. This email is to know if there is any other way to
solve my problem.
I want to have a component which has a simple EventListener to that goes
to
the server and changes some values in the client (typical ajax). The
problem
is that this component doesn't have a form, the component finally will be
inside a form, but is not defined in the component itself and the name of
the form can change.
As far as I understood, we cannot use the nice EventListener to receive
information (value of the input types) from the browser except we specify
the form name, but in my situation the form name will change every time
and
I need to define this as a parameter or have a default value for example
the
enclosing form for the event source...
I think this, maybe, can be done with some javascript, maybe
tapestry.form.submitAsync(form, content, submitName, validate)...But I'm
not
sure.
Another question, is if this can be done in that way?
BTW, I'm working with Tapestry 4.1.2, jdk 1.5 and tomcat 5.5.
Thanks you in advance,
robert
