Reflect filter does not flip vectors unless there are returned by inCD->GetVectors()
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I thought the usage of SetActiveVectors or SetActiveScalars() was considered obsolete in ParaView, since there cannot be more than one such DataArray at a time. Filters such as vtkReflectionFilter which do a GetVectors() to find the vector to flip ignore all other vectors which are simply copied via outPD->CopyData(inPD, i, ptId);
this is a bug, and results in wrong streamlines and all other vector displays in reflected surfaces in ParaView.
