Summary0011716: Reflect filter does not flip vectors unless there are returned by inCD->GetVectors()
DescriptionI 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.
Steps To Reproduceload the supplied file with vector "CF". Reflect across Z axis and display vector glyphs or streamlines. They are wrong on the reflected side.

Still an issue. It seems the origin of the problem is that the vtkDataSetAttributes::VECTORS attribute is not used properly in some readers and filters(?).
A workaround in ParaView for surface vectors is to use the Surface Vectors filter, which sets the VECTORS attribute. For volume vectors there is no such workaround.
