I am working on publishing a web service that will interface our EHR with an external lab provider.  After setting up much of the routines and code, I wanted to introspect the CFC’s I had created to see how they looked.  While there are several tools available to do this, I decided to use the built-in CFC Explorer provided with ColdFusion.  I navigated to my CFC in the browser, but all I got back was a blank page. Nothing else, wasn’t even asked for the RDS password.  I tried this on several other CFC’s with the same result.  I figured there may be an issue with the CFC Explorer itself, so I navigated directly to it by visiting http://localhost/CFIDE/componentutils/cfcexplorer.cfc.  When I did I got the RDS password prompt.  I entered the password and the explorer details presented.  I went back to my original CFC and refreshed, and all of the introspected documentation became visible.  Restarting my system probably would have fixed this also (I know, always restart), but it’s good to know that this method worked as well. 

So if you find yourself with a blank page when visiting your CFC, try hitting up the explorer first.
