Beginning Error in n-tier application of ORM?

[Cole]

Hey all,
I am getting an error when I attempt to do a basic "Customer" insert using the Telerik ORM in a website.

I have 4 facets to my site...

TestProject.Web
TestProject.Data
TestProject.Services
TestProject.Test

TestProject.Data has the objects created by the wizard in the DB->classes approach.  TestProject.Services is the location of my actual code for using the object.  For example, the web has an IAuthService which has a method "InsertTestSubject()" which is...

public bool InserTestSubject() {
            IObjectScope scope = Database.Get("DatabaseConnection1").GetObjectScope();
            //you could see in some expamples that this can also be done with
            //Database.Get("DatabaseConnection1").GetObjectScope();
            //there is absolutely no diference
            using (scope)
            {
                scope.Transaction.Begin();
                Customer c = new MyProject.Data.Model.Customer();
                c.FName = "Joe";
                c.LName = "Test";
                c.PassEncrypted = "testpass";

                scope.Add(c);
                scope.Transaction.Commit();
            }
            return true;
        }

When I run this code in my website I get the following error:

Server Error in '/' Application.

Can anyone assist me in what I am doing wrong?  After the above method I woudl assume I delegate all the work to the Telerik ORM tool.

Hello Robin,

I am unable to resolve the problem only by looking at the code snippet you have posted. Please send us a support ticket and attach your app.config and reversemapping.config files in a zip archive so I can evaluate the error.
