[Paraview] Instanciating an unknown type

[Fred Fred]

Right, vtkDataSetAlgorithm::RequestDataObject() seems to do the job but now I have another problem: the point data are no longer copied to the output.
Here is my code, what is wrong?

  // get the output
  vtkInformation *outInfo = outputVector->GetInformationObject(0);
  vtkDataSet *output = vtkDataSet::SafeDownCast(outInfo->Get(vtkDataObject::DATA_OBJECT()));

  // pass all associated data to output dataset
  output->CopyStructure(this->input);
  output->GetPointData()->PassData(this->input->GetPointData());
  output->GetFieldData()->PassData(this->input->GetFieldData());

and another question: is GetFieldData() the same as GetPointData() + GetCellData() ?

vtkDataSet* output = input->NewInstance();

vtkDataSetAlgorithm::RequestDataObject() already does this though. You shouldn't need to. See that method for details.

My problem is as follow: I am writing a vtkDataSetAlgorithm filter and I need to create the ouput dataset, which must be of the same type as the input.
Is there a one-line way to do it, ie avoiding if (input->IsA("vtkPolyData") output=vtkPolyData::New(); else if ... ?
