Oralce: Why Do Triggers on Editioning Views in My Custom Schema Fail?
I think I figured it out. I believe this is by design. I tested this and it works.

INSERT INTO my_table#
  (field2,
   field3) 
VALUES
  ('TEST', 1234)


I believe the intention is that source code be modified to either directly reference the # view. Or reference a synonym that points to that view. I know, people are saying "reference an apps synonym" all over the web, but I didn't connect why until just now. Hope this is useful to the rest of you all.
