to leave your transactions open indefinately which is an IB-no-no to most.
If a user opens a form to see some information and walks off to lunch, the
transaction stays open even if they change no information. Isn't that
considered taboo? To me, I see no problem except in the OIT-OAT comparisons.
And even at that, unless a change is made, it doesn't affect the OIT, right?
I just can't see myself going through and changing all my data-aware stuff
to non-data-aware simply to be able to close the transaction when
reading/browsing. I already close it whenever the user goes to a different
record so I really can't see the advantages of going beyond that but maybe
I'm just missing something.
