As you can see, I perform a GET request on the AddressComponent
directly, I think that is where I'm wrong, because doing this does
get AddressComponent as the root component where it was a
subcomponent before, the text field names are completely out of
context once the DIV is reloaded.
The solution was quite simple, I just had to configure the "name"
binding to a unique string in the form. WebObjects is no longer
responsible of the field uniqueness, but every bindings still works.

I guess this is a traditionnal question about webobjects, but I
did not find an answer in the archives and AJAX frameworks I found
are poorly documented, since I am a beginner, I did not succeed to
use them.
The problem is quite simple, I have a page containing :
- 1 WOPopUpButton with a list of 60+ countries
- 1 DIV containig WOTextFields with the address parts for the
chosen country (City, state, Zip, etc...)
This div is a WOComponent (AddressComponent) I call in my page,
with an "address" binding, according to the country set in the
address, it diplays the different field for that country.
The reason why I'm doing this is that I want to avoid reloading the
whole page, I want my site to be the very ergonomic, and I want to
be able to dynamically reload DIV containins dynamic WO elements.
When the page is initially requested, it embed the
AddressComponent, and everything works fine, I can submit the form
and bindings are fully functionnal.
Then I change the country, the changeCountry method is called (see
javascript attached at the end of the mail).

For example, this text field in the original page
<input size="15" type="text" name="7.6.1.4.0.CityComponent">
becomes :
<input size="15" type="text" name="1.4.0.CityComponent">
I hope things are a bit clearer and you will be able to help me :-)
<script type="text/javascript">
function changeAddressCountry(code)
{
http = getHTTPObject();
http.open("Get","<webobject name="ResourceURL1"></webobject>?
countryCode=" + code,false);
http.send(null);
if (http.status==200) {
var div_handle = document.getElementById("address");
if(div_handle){
div_handle.innerHTML =''+http.responseText;
alert(http.responseText);
}
}
}
function getHTTPObject() {
var xmlhttp;
/*@cc_on
@if (@_jscript_version >= 5)
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (E) {
xmlhttp = false;
}
}
@else
xmlhttp = false;
@end @*/
if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
try {
xmlhttp = new XMLHttpRequest();
} catch (e) {
xmlhttp = false;
}
}
return xmlhttp;
}
