RIA Debugging and ColdFusion (forgotten feature)

Some of you might remember Simeon Simeonov from the early days of ColdFusion. He was one of the original engineers and the architect of ColdFusion at Allaire. Needless to say, he is responsible for many of your favorite features in ColdFusion.

Sim, has recently posted a great blog post about the problems debugging RIA applications. And a possible solution. Definitely worth a read.

However, there is one more way to do debugging missing from his post (unless it's been updated). One of the last things I added to ColdFusion 7.0.2 before I left Adobe was to make sure all of the ColdFusion debug data is sent with every Flash Remoting request.

This is one of the more common forgotten features in ColdFusion. If you are using ColdFusion with Flex, you can still get all of the information you are used to seeing at the bottom of a regualar .cfm. To turn this on, just turn on debugging in the cfadmin. And then in your result event, you can look at the result event header to see all of this information; sql, execution times, variables, etc..

Way back when, on mikenimer.com I posted a flex dump component that does know how to format this debug data. However, to be honest. I haven't opened the component in the latest versions of flex so the component might need to be tweak to work in flex 3.

But that's no excuse not to monitor this data. With RIA apps it's more important than ever to monitor your requests. It's too easy to write a bad query and not know it, since you can't easily see this debug data. But it's worth a little extra work.
