One little caveat when working with CFBuilder is that I was not getting the file preview working on the IDE because it was complaining that my project was not the root of the selected server as you can see below:


The problem is that Builder knows the root of the server but my application project is not on the root of server but on a folder embedded in it.  So in order to make this work, just add a URL prefix to the project.  Right click on the project and click on  "SET URL Prefix":

Click on it and you will get the following dialog and fill out the FULL URL, I tried just the directory, but it did not work, maybe a bug in Builder. So put the FULL URL.

Hope this helps, enjoy!
