Hi,
I'm looking for a general solution to avoid constructs like this in all my
event handlers:
Object onMyAjaxEventHandler(){
do_some_processing();
if(request.isXHR()){
return zone.getBody();
}
return null;
}
Taha's @XHR annotation is a step in the right direction, but
Hmm, apparently the code was filtered out but is included here:
http://tapestry.1045711.n5.nabble.com/XHR-isXHR-shortcut-tp3353416p5713607.html
I'll try posting it again:
// Code begin
public class ZoneWorker implements ComponentClassTransformWorker2 {
protected Request request;
Hi
The reason the body is invoked is because there may be some logic which must
be executed even if the call is not ajax. The worker only ensures that if
javascript is disabled the call may still go through.
Regarding the return value, i modified the code to include cases you had
pointed out.
Thanks Thiago
You are absolutely right, in case of void it can throw an exception, i will
modify it and put it in my examples at

Why not Apache Extras
I suppose this is useful, but what it does is to invoke the method
regardless of whether XHR is true or not, and then throw away the result.
It probably should be:
if (request.isXHR()) {
invocation.proceed();
}
I'm not sure what the else should be ... probably return null/0/false
