Showing much tidier to populate an array of structs
l.response.body.result = ArrayNew(1);
for(l.i=1;l.i lte l.events.recordcount;l.i = (l.i + 1)){
arrayAppend(l.response.body["result"], {
"id" = l.events.id;
"start" = DateDiff("s","1/1/1970",l.events.startdate) * 1000;
"end" = DateDiff("s","1/1/1970",l.events.enddate) * 1000;
"title" = l.events.title;
"class" = "class";
"url" = l.url;
});

Very basic treatment of deferring the processing of a job, with callback handlers and monitoring functions.
<cfscript>
public struct function defer(required function job, function onSuccess, function onFailure, function onError, function onTerminate){
var deferThread = "";
try {
cfthread.status = "Running";
thread name="deferThread" action="run" attributecollection=arguments {
try {
successData.result = job();
cfthread.status = "Completed";

adamcameron / cfparam.cfm
Created October 28, 2013 16:30
Demonstrating bug 3364510. The cfparam.cfm example raises an exception if URL.required is not set. This is expected behaviour. The param.cfm example does NOT raise an exception. This is wrong. Tested on CF 9,0,1,274733 and 10,0,11,285437: both have same failure Also tested on Railo 4.1.1.009: it works fine; and OpenBD 3,1: also works fine
<cfparam name="URL.required">
Don't output this unless that required variable is set
