ColdFusion CFTextArea isn’t compatible with Microsoft Edge
I just upgraded CKEditor so that it will function better with Microsoft Edge. I hadn’t used ColdFusion’s CFForm or CFTextArea since CFMX6 and wondered if it had been updated since... especially considering that ColdFusion 12 is currently being developed.
It appears that ColdFusion 9, 10 and 11 all come integrated with FCKEditor v2.6.4.1 from 2009 and it doesn't work with Microsoft Edge (even though it does work with Firefox Developer Edition.) I hope this outdated javascript library gets replacement consideration before CFv12 is released. It really should have been updated in ColdFusion 10 & 11, but based on past bug reporting experience it won't be addressed and developers should avoid using all CFUI tags and use CKEditor instead.
