Hi Niels,
I've updated the example for the 8.04 build. Seems to be a while since that one was updated.
The Redactor seems to be working ok - but make sure the individual text field is set to use either the "default" or "redactor" editors. I strongly recommend setting the text field to "default" because then you can control which editor is used from the WebServer procedure (ie one setting for the whole program.)
On the web server, turn on the Redactor script, and set the default editor to be Redactor.
I'll fix the TinyMCE for the 8.04 release, which should be out soon, and then you can change back if you like using the Webserver setting.
cheers
Bruce
