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

No, it may very well be a bug. I wouldn't be surprised at least. I'm
still busy trying to refactor/etc the For component to work under
these "dynamic" conditions a little more friendlier but if a bug is
filed I will have a much better chance of remembering. (whereas emails
to this list are only likely to have about a 10-30% chance of being
fixed unless I run into them myself ;) )
