Came across an interesting bug today with CFTEXTAREA. Not a bug with ColdFusion, but a bug with the Homesite update files from Adobe. Below is how Homesite filled in the tag using their WYSIWYG:
As you can see, it has enabled="Yes", and disabled="No". Kind of strange to have them both as options, and I've never really recognized it before this problem came up. I had simply updated my Homesite files with the tag and help files from Adobe.
When I went to submit the form, the "commentmessage" form variable was not passed in the form scope. I believe this is from the browser interpreting having "disabled" anywhere in the textarea.
I simply removed both variables(since ColdFusion defaults CFTEXTAREA to enabled="yes"), and all is well.
Hope this helps someone out there.
