Rave: CustomConnection zur Laufzeit hinzufügen?

[Errraddicator]

Ok, habs rausgefunden:

Delphi-Quellcode:

procedure TIWUserSession.generatePDF(pdfName: String; ravName: String);
var
  rvProject: TRvProject;
  rvSystem: TRvSystem;
  rvPDF: TRvRenderPDF;
  rvCcOutputs: TRvCustomConnection;
  dvOutputs: TRaveDataView;
  dcOutputs: TRaveDataConnection;
  rvPage: TRavePage;
  bndOutputs: TRaveDataBand;
begin
  // init components
  rvProject   := TRvProject.Create(self);
  rvSystem    := TRvSystem.Create(self);
  rvCcOutputs := TRvCustomConnection.Create(self);
  rvPDF       := TRvRenderPDF.Create(self);
  // apply event-hanlders to custom-connection
  rvCcOutputs.OnEOF     := rvCcOutputsEOF;
  rvCcOutputs.OnFirst   := rvCcOutputsFirst;
  rvCcOutputs.OnGetCols := rvCcOutputsGetCols;
  rvCcOutputs.OnGetRow  := rvCcOutputsGetRow;
  rvCcOutputs.OnNext    := rvCcOutputsNext;
  rvCcOutputs.OnOpen    := rvCcOutputsOpen;
  // modify custom connection
  rvCcOutputs.DataIndex := 0;
  rvCcOutputs.DataRows  := outputSets.Count;
  // modify system-properties
  rvSystem.SystemOptions  := rvSystem.SystemOptions - [soShowStatus];
  rvSystem.SystemSetups   := rvSystem.SystemSetups - [ssAllowSetup];
  rvSystem.DefaultDest    := rdFile;
  rvSystem.DoNativeOutput := false;
  rvSystem.RenderObject   := rvPDF;
  rvSystem.OutputFileName := pdfName;
  // modify project
  rvProject.Engine      := rvSystem;
  rvProject.ProjectFile := ravName;
  rvProject.Open();
  // build & modify data view for the report
  dcOutputs := CreateDataCon(rvCcOutputs);
  dvOutputs := rvProject.ProjMan.NewDataObject(TRaveDataView) as TRaveDataView;
  dvOutputs.Name           := 'dvOutputs';
  dvOutputs.ConnectionName := dcOutputs.name;
  dvOutputs.DataCon        := dcOutputs;
  CreateFields(dvOutputs, nil, nil, true);
  // get data-band & apply data-view
  rvPage     := rvProject.ProjMan.FindRaveComponent('Report1.Page1', nil) as TRavePage;
  bndOutputs := rvProject.ProjMan.FindRaveComponent('bndOutputs', rvPage) as TRaveDataBand;
  bndOutputs.DataView := dvOutputs;    
  // execute report
  rvProject.Execute();
  // reset report & custom-connection
  rvProject.Close();
  rvCcOutputs.DataRows  := 0;
  rvCcOutputs.DataIndex := 0;
end;

Das behebt mein Problem aber leider immer noch nich. :-/
Das 1. Dokument is nach wie vor einwandfrei, beim 2. passiert gar nix mehr.
