Input string was not in a correct format

I am getting a problem when wrting tests for some of our modified .netTiers DAL and cannot seem to figure out what is causing the problem.

I have managed to narrow this down to the following two code samples

When I run the following Test it fails

        [TestMethod]
        public void Load_Test_Problem1()
        {
            OracleVWE_STB_BOOKMARKProvider target = new OracleVWE_STB_BOOKMARKProvider("Test", true, "Test");

            VWE_STB_BOOKMARK entity = new VWE_STB_BOOKMARK();

            entity.STB_ID = Int32.MaxValue;
            entity.STB_NOTE = String.Empty;

            MockManager.Init();

            Mock MockTransactionManager = MockManager.MockObject(typeof(TransactionManager));
            TransactionManager ObjMockTransactionManager = (TransactionManager)MockTransactionManager.MockedInstance;

            Mock MockOracleCommand = MockManager.MockObject(typeof (OracleCommand));
            OracleCommand ObjMockOracleCommand = (OracleCommand)MockOracleCommand.MockedInstance;

            object STB_ID = entity.STB_ID;
            object STB_NOTE = entity.STB_NOTE;


            using (RecordExpectations recorder = RecorderManager.StartRecording())
            {

                IDataReader reader = Utility.ExecuteReader(ObjMockTransactionManager, ObjMockOracleCommand);                

                recorder.ExpectAndReturn(reader["STB_ID"], STB_ID);
                recorder.RepeatAlways();

                recorder.ExpectAndReturn(reader["STB_NOTE"], STB_NOTE);
                recorder.RepeatAlways();

            }

            IDataReader readertemp = Utility.ExecuteReader(ObjMockTransactionManager, ObjMockOracleCommand);

            int temp2 = Convert.ToInt32(readertemp["STB_ID"]);

            MockManager.Verify();
            MockManager.ClearAll();
        }

However when I swap around a couple of the expectations it passes.

        [TestMethod]
        public void Load_Test_Problem2()
        {
            OracleVWE_STB_BOOKMARKProvider target = new OracleVWE_STB_BOOKMARKProvider("Test", true, "Test");

            VWE_STB_BOOKMARK entity = new VWE_STB_BOOKMARK();

            entity.STB_ID = Int32.MaxValue;
            entity.STB_NOTE = String.Empty;

            MockManager.Init();

            Mock MockTransactionManager = MockManager.MockObject(typeof(TransactionManager));
            TransactionManager ObjMockTransactionManager = (TransactionManager)MockTransactionManager.MockedInstance;

            Mock MockOracleCommand = MockManager.MockObject(typeof (OracleCommand));
            OracleCommand ObjMockOracleCommand = (OracleCommand)MockOracleCommand.MockedInstance;

            object STB_ID = entity.STB_ID;
            object STB_NOTE = entity.STB_NOTE;


            using (RecordExpectations recorder = RecorderManager.StartRecording())
            {

                IDataReader reader = Utility.ExecuteReader(ObjMockTransactionManager, ObjMockOracleCommand);                

                recorder.ExpectAndReturn(reader["STB_NOTE"], STB_NOTE);
                recorder.RepeatAlways();

                recorder.ExpectAndReturn(reader["STB_ID"], STB_ID);
                recorder.RepeatAlways();
            }

            IDataReader readertemp = Utility.ExecuteReader(ObjMockTransactionManager, ObjMockOracleCommand);

            int temp2 = Convert.ToInt32(readertemp["STB_ID"]);

            MockManager.Verify();
            MockManager.ClearAll();
        }

Is anyone able to explain this to me or have I found a bug?


The Error I am recieveing is:
