RE: A couple of OSUser questions

Re: [Opensymphony-developers] A couple of OSUser questionsI didn't realize
we where talking about using <composite-id>, as I agree, we shouldn't use
it.  However, the magic of Hibernate is that if my user requires it, then in
my implementation I can use a <composite-id> as long as my mapping loads
instead of the default one.

I think that all he meant was to use Long versus long as the id, which would
still have the same mapping...

  As quoting from Hibernate Documentation:



  "There is an alternative <composite-id> declaration to allow access to
legacy data with composite keys. We strongly discourage its use for anything
else."



  Can we please hold off applying the foreign PK patch until more people
have chimed in?



  Cheers,

  Brian,



  I actually lean towards the PK being an object as well. I prefer to be
able

  to know that getting a PK which is null means it hasn't been saved, versus

  knowing the 0 means unsaved. Especially as 0 is a perfectly good ID value!




  Which bug report was yours? I'll look at your patch and apply it, do you

  just want to one patch for all your changes?

  Hi all,



  Back from some extended time away from the keys. Doing some

  travel and

  carpentry and things of that nature. It's fun to be back.

  Hope all your

  holidays are going well.



  Just getting recent versions of the code down and was psyched to see

  Hibernate support in OSUser. I've been working a bit with it

  in the last 24

  hours and filed one bug on it last night. I have the fixes

  for it, but it

  will take longer for someone to use them than it will for

  someone with IDEA

  and a RW connection to CVS to do the changes over again. It

  took me about 30

  minutes on this side.



  The other one, I'm not so sure it's a bug or not, it smells a

  lot like it

  belongs in the space of "conventions" rather than bug. So I

  thought I would

  ask for some rationale.



  In the CMP world, primary keys are objects instead of

  primitives. I've been

  following that through to Hibernate since it looks like

  composite types

  require that as well. But BaseHibernateEntity defines the PK

  as a primitive

  long.



  Any comments on why this would be beneficial? Otherwise, my

  vote is to

  convert to object PKs and am happy to do the work on it.



  thanks,



  -b
