Codito Ergo Sum

I maintain some code that made use of InterAKTs WYSIWYG HTML editor. After the coldfusion 8 roll-out, I was getting strange errors on several pages, with this in my logs:

java.lang.StackOverflowError

- repeat like 500 times or so -It turns out that the cflib.cfm file that interAKT used has several functions in it that conflict with same-named CF8 functions. All you need to do is comment several of the cflib.cfm functions, and presto worko! Here is the cflib file included so you can copy / paste it (I take no credit for this work, I simply commented out several functions to not conflict with CF8!)
