Rick if there is an error being thrown then the log files are important here.
An other thing to note is that it might pay to look at something like this. http://www.andyscott.id.au/2011/8/27/ColdFusion-and-Remote-Calls-and-notifying-the-caller-of-the-problem This is how I handle all Ajax calls, so that the client can then decide on what to do if it succeeds or fails. So in the case of a failure you could then display a human readable error or notification that could be reported to you, but the biggest part of this entire equation will be error logging using the <cflog /> or even emails for sending important information if need be. -- Regards, Andrew Scott WebSite: http://www.andyscott.id.au/ Google+: http://plus.google.com/108193156965451149543 On Wed, May 2, 2012 at 3:48 AM, Rick Faircloth <r...@whitestonemedia.com>wrote: > > Looks like a good solution for getting some error clues > back from AJAX calls.
