I'm using arc gis 10.2.1. I have 2 programs that are editing SDE.DEFAULT at the same time, creating features in 2 different versioned feature classes. What I find is that when the second program to save its edits gets an exception with the message "The version has been redefined to reference a new database state. [SDE.DEFAULT]". I've tried various reconcile calls at this point to allow me to save the edits in the second program but nothing works. I can't combine the 2 programs because one of them is someone else's code that's beyond my control.
