It is a bit curious how all this happened, because they had announced with the release of CF2016 that they were merely going to 'deprecate' (not obsolete) these things as of CF2016. The good news (for those who need this to work, as part of a move to CF2016 perhaps, where they want to minimize effort in making the move), that Adobe blog post (and a related technote) offers a link for you to download that YUI library to put the feature back. This is discussed in the Adobe blog post about this new installer in December 2016. They also removed the libraries supporting the Spry and portlets features. If the one from Dec 2016 (or later), you will, because Adobe removed the underlying javascript library (YUI) that supported this calendar (and some other UI elements). If the original from Feb 2016, you won't see this. The first issue, where it doesn't work at allĪs for the first problem, where the calendar just doesn't work at all on CF2016, again this is based on which installer you are using. And of course, this could also happen if you're moving to CF11 or 2016 for the first time, and someone else had 'fully updated' those to that update level before you started testing against it. The second problem was introduced in those two named updates, and was fixed in the very next updates (CF11 update 13 or CF2016 update 5).

(If you install or installed CF 2016 from the original installer in Feb 2016, you won't see this problem as it wasn't removed then.) The first problem was introduced in the CF2016 installer released in Dec 2016, and any after that, where Adobe has literally removed the library used for the calendaring, but you can add it back, as I discuss below. If you're using the cfinput type='datefield' feature to popup a calendar and are finding that it's a) not working *at all* in ColdFusion 2016 or b) it showing up but not *correctly* after ColdFusion 11 update 12 or ColdFusion 2016 update 4, there's a fix for both. And I may revise the content as necessary. Corrections are welcome, in the comments. Same with links and subsequent comments from myself or others. Some content may be outdated-though not necessarily.
