In our WinForms application, we are using role-based security. I can only save security changes via either the SecurityDialog or UserEditor when connected to our SQL Server 2008 database through Enterprise Server. If I connect to the same database without Enterprise Server it will result in an exception on saving:

MicroFour.StrataFrame.Business.BusinessLayerException: An error occurred while saving an the data to the server. ---> MicroFour.StrataFrame.Data.DataLayerSavingException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.

We correctly set the key stuff here in Program.cs:

SecurityBasics.SecurityDataSourceKey = MyApp.SecurityDataSourceKey;

SFSPreferencesBO.RetrieveSecurityPreferences();

            

//-- Set the encryption key and vector for the user data

SecurityBasics.SetSecurityKeyAndVectorForUserAuthentication(MyCompany.MyApp.SecurityKey);

We also data deploy all the SFS* tables to this database in the DDT. Any ideas on why this may be happening?



Thanks,

Derek,

When you were debuggin through that, which variable had a null reference?  That will help me reconstruct what's happening.  Thanks.
