Hello all,

the following behavior just surprised me a bit: ;-)

When creating a new instance of an OM object, setting the pk maually and saving
it, the PK will be ignored. If a id method is specified, the pk will be retrieved from
there (e.g. Oracle Sequence).

When specifying the values via a Criteria object, I can set the PK and it will be
considered when saving. If the PK already exits, the DB throws an error, certainly.

Here's the example code:

  // when saving an author, pk is ignored
  Author a1 = new Author();
  a1.setAuthorId(999);
  a1.setLastName("Knallinger");
  a1.setFirstName("Ingnoratio");
  AuthorPeer.doInsert(a1);
        
  // by criteria, pk will be used
  Criteria c = new Criteria();
  c.add(AuthorPeer.AUTHOR_ID, 999);
  c.add(AuthorPeer.LAST_NAME, "Knüllinger");
  c.add(AuthorPeer.FIRST_NAME, "Karl");
  AuthorPeer.doInsert(c);

Is this behavior considered to be correct (what is the background, then), or not?


Daniel
