after.commit.transaction hook in DAL replaces after.update.db.commit.

However, I've observed that is does not work as one would expect. Before.save.object and after.save.object work as expected. When record (X) is updated by user, then those hooks are correctly called --- for record X, but continue debugging, hook after.commit.transaction is finally called, but for record W ( the first record displayed on the form (top) ). Record X was #2

Note, form type 3 grid. I expect the hook is designed to be called generally but it makes no sense. I suppose the work-around is to use synchronized dialogue with detail session, but I don't want to.

Any comments or advice?
Thanks
