For some reason Adobe is no longer supporting ColdFusion in the new Dreamweaver CC 2014. CF comments are no longer are highlighted in the code view. In fact CF is not listed among applications, although PHP is. Is Adobe planning on abandoning CF?
Ben Forta wrote a post on his blog last year about the changes to Coldfusion and Dreamweaver.
You can see it here - http://forta.com/blog/index.cfm/2013/6/30/On-Dreamweaver-CC-And-ColdFusion
The main reason seems to be Coldfusion Builder and moving Dreamweaver to do the "client side" aspect of development.
Forta gives a good explanation in his blog. (Thanks for the link). However, I agree with many of the comments that indicate Adobe management has their head in the sand.
My biggest gripe is no longer highlighting CF comments in the code. I do most of my coding by hand.
