I deliberately did not answer Yann's question about the DIV, even
though what he does would be pretty trivial with the Ajax framework
just because I wanted to see if anyone would take a heart and does it
for me. No, not you Mike! Anyone who has at least some understanding
of WO and has looked at the Ajax example should be able to explain to
him.
And this person(s) is also more than welcome to write up some better
comments for the Ajax example explaining a bit more in-depth what is
going on and why.
Cheers, Anjo

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).
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.
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;
}
</script>

Can you let me know what the javascript is trying to do? Is it to
edit
the address in the particular format for that country?
Depending on what you are trying to do it may be better to not use
Javascript - either way it might be best to get it working using
normal wo actions and then try to do it with javascript.

Thanks to Miguel and John for their usefull answers.
The result is I make a big red cross to my idee to programmatically
generate components :-)
Using WOSwitchComponent, I'm almost successfull implementing exactly
what I want, but I have a problem with the dynamic part of the code
(the javascript that realods a DIC content).
When my page is loaded, the components hierarchy is a full page with
my header, the global component, my address component, each field in
it, etc...
But when I use Javascript to get a new form for the new address
format, it is completely out of the context, and for example, my
City
text field that look like this in the code with the original
request :
<input size="15" type="text" name="7.6.1.4.0.CityComponent">
Become that after the DIV update :
<input size="15" type="text" name="1.4.0.CityComponent">
As you can see, since the root component is itself, the identifiers
are wrong.
How can I deal with that ?
