InvalidCastException

[rhodri80]

Hi
This is an issue that has been reported before but we are getting this error in out nunit test run from Resharper. This seems to crash the second time we call dataProvider.Stub(p => p.GetDataAccessor()). There does not seem to be much difference in the arguments passed. We rebuilt rhino mocks from the latest code but now it fails although the code does not appear to have altered significantly.

var dataProvider = MockRepository.GenerateStub();
var dataConsumer = MockRepository.GenerateMock();
var calculationEngine = MockRepository.GenerateStub();

        var configuration =
            new AnalysisConfiguration
            {
                Calculations = new ICalculationInstance[0],

                Switches = new IConnectionSwitch[]
                               {
                                   new ConnectionSwitch
                                       {
                                           Name = "Switch1",
                                           InputSelector = controlData => controlData["SwitchInput"] as string,
                                           MissingInputIsError = false
                                       }
                               },

                DataConnections = new IDataConnection[]
                                          {
                                              new DataConnection(
                                                  new ConnectionEndPoint(PortType.Source, "Matrix2", "A"),
                                                  new ConnectionEndPoint(PortType.SwitchControl, "Switch1", "SwitchInput")),
                                              new DataConnection(
                                                  new ConnectionEndPoint(PortType.Source, "Matrix1", "A"),
                                                  new ConnectionEndPoint(PortType.SwitchData, "Switch1", "Default")),
                                              new DataConnection(
                                                  new ConnectionEndPoint(PortType.SwitchData, "Switch1"),
                                                  new ConnectionEndPoint(PortType.Output, "Matrix O", "Result 1")),
                                          }

            };

        Func<object[]> matrix2AData = () => new object[] { "PortThatIsNotThere" };
        dataProvider.Stub(p => p.GetDataAccessor("Matrix2", "A")).Return(matrix2AData);
        Func<object[]> matrix1AData = () => new object[] { "DataToPassThroughSwitch" };
        dataProvider.Stub(p => p.GetDataAccessor("Matrix1", "A")).Return(matrix1AData);
