Hi All
Any thoughts on how to address this problem
I have a multi instance app that connects to a single data store.
For any user, across the instances, I need to increment a numerical value newly for each new registered user.

This then has to be saved back to the data store and for there to be no conflicts with similar values for new registrants...

Any ideas or have I missed something easy here..

It is possible to use the EOF primary key generation support creatively to generate things that aren't primary keys.

EOAdaqptorChannel.primaryKeysForNewRowsWithEntity(int count, EOEntity entity)
