[Paraview-developers] Bug in my reader plugin

[Lodron, Gerald]

Hello

I made a reader plugin which returns a vtkPolyData object from our internal file type and have following problem:

Open our file using plugin, polydata object is successfully loaded and visualized (everything fine)
Select some region with "select points through"
Apply the ExtractSelection filter, the subset is successfully extracted (unstructured grid), everything seems fine
Select Preserve Topology check box in the ExtractSelection object panel
Apply again

Then following comes into output window:

Warning: In D:\Develop\Source\ParaView-v4.1.0-RC1-source\ParaViewCore\ServerManager\Rendering\vtkSMPVRepresentationProxy.cxx, line 279
vtkSMPVRepresentationProxy (10CE2020): Could not determine array range.

Someone knows what I am doing wrong, this does not appear when I load a normal vtkPolyData .vtk file format so it seems that I am doing something wrong with the reader plugin interface, but what.....

Thanks
