[AWS] How to update forms dynamically

Yes, I need to send all the fields filled out for user validation. My program 
will not generate the HTML web page containing the form.  Here are the steps.
1) User clicks on a URL link on the browser.
2) The browser automatically displays the HTML page containing the form (an HTML file 
    with the form initial values). 
3) At the same, my program will need to update the form values (replace initial values). 
    I don't want my program to send back the entire HTML with the values filled out.  I just want to 
    update the form data values that is currently being displayed (from step 2).  Of course, the 
    program will have knowledge on the form control names (id= or name=).

Which demo supports using AWS/AJAX for changing web page content without reloading everything.
Is it the demos that utilizes the SOAP packages?
 
Thanks again for your help,
Alex

Good.

You want the Form to be sent back to the user (for validation?) with all
the fields already filled, right? If this is the case just send back the
form with the proper value="" or content (for textarea) in the HTML,
won't this work ?

Another option is to use AWS/AJAX support. You can change the web page
content without reloading everything. In both cases makes sure you look
at the demos which covers all of this.

That's nice goal :)
