dynamic form
Hi,
I'm sure you know what I mean, but it is quite difficult to explain...
I want a form where you have 2 select fields.
The first field is the most important select.
When I select a field, I want the second select to appear with the possible
values corresponding the first select.
The code works if I press the submit button. Then the second select is
automaticly filled in with the correct value. I want this functionality
without pression the button...
Any ideas?

I will first use the submitOnChange, because the need of time is extremely
large. Later on I will implement it by using JavaScript...
Thx everybody !

Which is a great suggestion other than my policy of deliberately tyring
to avoid any
and all javascript work ;)...However, if someone has most of the client
side work done,
I do think this could be turned into a rather elegant component on it's
own. The RC
could then be shared or added to the "contrib" library.

Once you have the following working, you may want to
take the Tapestry spirit and make the component
reusable. Chapter 8.2 of Tapestry in Action is a good
starting point.

Re: dynamic form

This is usually achieved via Javascript. You would give the page object
methods to provide access to the collections that you with to use. You
would then use the collections via foreach and insert components to
generate a Javascript data structure such as an Array of Arrays or Hash
of Hashes. In the select components onClick event you would then
dynamically change the contents of the select list. So the only
interaction with Tapestry per se would be giving the page object a
method to generate the list, and I'm taking a liberty of assuming you
are using a database....If you do not have the need for a data driven
approach you could simply hardcode all the values into the HTML page or
javascript file. If you look around you will find many examples of how
to do this. You need to have a fundamental understanding of DOM
manipulatioin via Javascript before you go about implementing this.

Quick solution is to use the submitOnChange attribute of the
PropertySelection component. Though a more JavaScripty solution is
usually more desirable, perhaps using the hot XmlHttpRequest feature to
get more data if its too much to send down in the first render.
