Our editor will replace only the "Multiple lines of text" (RichTextField) column type for editing HTML. The "Publishing HTML" site column type (RichHtmlField) is not supported in lists. I think the problem is that SharePoint does not allow us to override the RichHtmlField rendering template, which is why we only override the RichTextField template. We are currently working on a workaround for this problem and support for the RichHtmlField will be added in a future RadEditor for MOSS release. I apologize for the inconvenience.
