I’m adding this for informational purposes since my testing has been fairly consistent with its results. If the document holding and embedded view is accessed in the views InViewEdit event, using notesuidocument, all calls to refresh, or close and reopen the uidoc cause the notes client to crash. This is just a tad limiting when you want to ensure the current document is correctly displaying all changes made to it, particularly if it has changed the category being passed to the embedded single category view !!
