No. I've got the problem for time registration. We got an exception that the transaction failed, so we do it again which can result in duplicate (and more) datastore entries which is bad. Because now there are duplicate bookings and so duplicate working time... It's a disaster that the program gets a transaction failed while the transaction didn't doing another insert resulting in a mess. But ignoring the exception can result in now datastore entry. So we have catch the exception, do a select and repeat the insert if it didn't happen by now. And that we have to do for any insert ...... I'm frustrated. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to google-appengine@googlegroups.com.
