Just a quick edit:
I've jsut added a response to be sent back and got the alert to
display the response so that is fine, with the response tab in FireBug
showing:
This is a response null;
/* !eval(new String('(' + this.header('X-JSON');)) */ null;
/* !eval(new String('(' + this.header('X-JSON');)) */
Thanks,
Paul
