URGENT! Crystal Caching Paramaters.

Hi,

Using Coldfusion i'm calling a report that is run so frequently that i'm keeping the object open.

                  if (Not StructKeyExists(Application, Attributes.Persist)) {
                        Application[Attributes.Persist] = StructNew();
                        Application[Attributes.Persist].o_CrystalReport = CreateObject('component', '#Application.DbSource#.nuReport');
                        Application[Attributes.Persist].o_CrystalReport.Init(Application.DbServer);
                        Application[Attributes.Persist].o_CrystalReport.OpenReport(Attributes.Report,'rassdk://');
                        Application[Attributes.Persist].o_CrystalReport.SetDatasource(Application.DBSource,Application.DbServer,Application.DbUser,Application.DbPass);
                  }
                  Application[Attributes.Persist].o_CrystalReport.RunReport(5,'#GetPrinter.Path##Attributes.JobId#',Attributes.Parameters);

So the only bit that gets run more than once is the last line which just calls the report which will already be open. The problem that i'm having is the report is always run with the set of parameters that were first passed, even though im passing the parameters on this line, theres a couple of sub functions, but here's the bit of code that sets the parameters, can anyone tell me how to replace the existing parameters.

                  for (i=1; i lte ListLen(Arguments.parameters); i=i+1)
                  {
                        result = ListgetAt(Arguments.parameters,i);
                        ParamCollection = getClientDoc().DataDefinition().ParameterFields;
                        ParamToChange = ParamCollection.Item(i-1);
                        NewValue = GetFactory().CreateObject("CrystalReports.ParameterFieldDiscreteValue");
                        NewValue.Value = result;
                        TempParam = GetFactory().CreateObject("CrystalReports.ParameterField");
                        ParamToChange.CopyTo (TempParam);
                        TempParam.CurrentValues().Add(NewValue);
                        ParamController = getClientDoc().DataDefController().ParameterFieldController();
                        ParamController.Modify (ParamToChange, TempParam);
                  }
