I'm not really sure this will be useful for any of you but I've just found and undocumented parameter in the refresh method of the notesUIDocument class.
This is what's in the Designer 7 & 8.5 Help:
Call notesUIDocument.Refresh( [ IncludeRichTextItems ] )
This is what the type ahead shows:
If you include that optional parameter the method will also refresh any embedded views or editors in the form.
Thank you IBM for allowing me to learn something everyday.
