Does anyone have this working in 5.0.3?  I'm trying to back-port, which seems pretty straightforward, but I can't get htmlArea to show up.

I'm trying to use it with ETP, and I've gotten to the point where it's including the references to the htmlArea JavaScript and CSS files.  So I know I have it at least partially set up.  However, it still displays a plain textarea input.

I've copied and/or made the changes to the richtext procs, acs-subsite/www/resources/core.js and to www/blank-master.tcl/adp, and I've set up the UseHtmlAreaForRichtextP parameter.  Anything I could be missing?
