Weird netsuite thing-of-the-day. I have a field that was originally long text, and is now rich text. Before changing it, I set up a workflow action (custom action that returns a long text parameter — because rich text is not an option for return type) and used it in workflow to set the value of my field. It’s still working, even though my field is now of type rich text, but I can’t set up that action again the same way — my field doesn’t appear in the drop-down on the action because it doesn’t match the return type.
