Form Component Question
Our web developer just asked me a question about the Form component that
I can't answer. The HTML rendered from the Form component seems to set
the name attribute to Form0. Is there a way to override this? I don't
see it listed in the documentation. If not, is the first tapestry form
component on the page always going to be named Form0?
Eg: we are getting
<form name = "Form0">
and we want:
<form name = "FooForm">
We are using Tapestry 2.3.
Thanks,
Matt Christensen

I suppose you should look to the source of org.apache.tapestry.form.Form. In
the version 2.4-alpha-5:
protected void renderComponent(IMarkupWriter writer, IRequestCycle
cycle)
{
String actionId = cycle.getNextActionId();
_name = "Form" + actionId;

That make sense. I'll have to take a look at the js subsystem. For the
page in question, we should be OK with Form0, since it's a login page
and won't ever have other forms on it.
It would be nice if the form name matched the component id, but I can
see why that would neither solve the fundamental problem nor be a simple
change to make.
Thanks for the help,

Tapestry has a subsystem for generating JavaScript from a template. It is
best to use that. You plug your form object into the script and custom
javascript is generated from it. This is the best approach to insulate
yourself from future changes to the framework or your application.
For example, what if some pages in your app include a little search form at
the top of the page? The becomes Form0 and your form will be Form1. You
can see this on the Workbench example, where the form at the bottom of the
page (that controls the debug output and the inspector) is sometimes Form0
and sometimes Form1 depending on the page ... of course, that detail is not
relevant to any of your code which is the whole point of Tapestry.
One thing I might consider is to change the default name of the form to
match the form's component id ... but this is not deterministic either,
since anonymous forms are common, and the form id may be suffixed with a
number to make it unique.
This is a trivial change to the framework ... but a pain in the ass to
update all the JUnit test suites!

I think the designer wants to use some javascript with it.
The exact name of the form is less important than that the form name is
deterministic -- that is, that we can always count on Form0 being Form0.

Is there a specific reason you wish to control the name of the form?
