The deferrable option on a constrainst is designed to solve the problem with

Hi!

Thank you to all who have answered!

The source of the problem here seems to be that we have a pk with meaning and by doing that we run into some issues when creating new objects. The design of the databasemodel is not in our hands in this project, so that is life :)

The example I posed yesterday was a bit to simple and I see that it didn't show our problems around this issue in any good way.

As a workaorund we are going to redesign the GUI in our app so that it not will be possible to insert/delete object without saving between each insert/delete.



-Kaj :)
