Re: [cgiapp] Returning multiple values with CGI::Ajax

[Bruce McKenzie <suppressed>]

Maybe I'm misreading what's you're trying to do, but if the user changes 
the date in one form, why not just distribute that value to the other 
two formfields with Javascript? You could do this with a CGI::Ajax 
callback if you wanted to have the server check the date first. I don't 
think CGI::Ajax was intended to deal with the multiple elements in the 
DOM, except via JavaScript.
