In version 2.4.2.3 this scenerio still worked. In 2.4.3 and 2.6 preview I ran into the above error. Reproducible: Always Steps to Reproduce: 1.Use DbProviderFactory 2.Use DbDataAdapter 3.Fill a DataSet Actual Results: Reproduction in attached project. Expected Results: Above exception I used Oracle 10g Enterprise database for the test. So cannot say if other databases can be used to reproduce the error. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ mono-bugs maillist - mono-bugs@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-bugs
