Shortly, after posting the previous reply in this thread, I encounterd this problem in SQLGEN 1.1. I changed the connection string in a file that I had been editing (and saving) and clicked Generate Data button.
The resulting report started with:
Object reference not set to an instance of an object. System.NullReferenceException: Object reference not set to an instance of an object. at e.a() at e.b() at t..ctor(ConnectionProperties connectionProperties, SDGTable sdgTable, CountAction countAction) at aw.a(CancellableController , Int32 , Int32 , ConnectionProperties , GenerateAction , SqlConnection , SDGProject , GenerationReport )
Repeated attempts in same session failed. Restarting the app fixed the problem.
