Run the following script:

SCRIPT
BEGIN

 EXECUTE IMMEDIATE
 ' CREATE TABLE "Activities"
   (
   "ID" INTEGER NOT NULL,
   "PersonID" INTEGER,
   "Name" VARCHAR(100) COLLATE "ANSI",
   CONSTRAINT "PrimaryKey" PRIMARY KEY ("ID")
   ) ';

EXECUTE IMMEDIATE
' CREATE VIEW A_NameList as
  SELECT
      PersonID,
      LIST(Name) as NameList
    FROM Activities
    GROUP BY PersonID
    ORDER BY PersonID ';

EXECUTE IMMEDIATE
 ' ALTER TABLE Activities
   RENAME COLUMN PersonID TO AuthorID ' ;
END;

Now use the EDBMgr IDE to open the view 
A_NameList, you will receive an error message "Field 
PersonID does not exist"

Now Run the following script

SCRIPT
BEGIN

EXECUTE IMMEDIATE
 ' DROP VIEW A_NameList ';

EXECUTE IMMEDIATE
  ' DROP TABLE Activities ';

END

You will receive an error message again. It is possible
to ALTER the view to remove the incorrect field, but 
not to drop it.
