[Paraview] Empty Object Properties - Custom Reader Plugin

[Xunlei Wu]

Hi Karl,

Thanks a lot for the tip. I followed vtkAVSucdReader.h/cxx and hoped to solve my issue. I understood vtkAVSucdReader:: CellDataArraySelection and vtkAVSucdReader ::PointDataArraySelection are responsible filling the "Cell/Point Array Status" window. However, I am not sure how these two arrays are interfaced. I have added these two arrays and corresponding access functions (Get/Set) in my reader class. I still do not see anything within "Cell/Point Array Status" window. 
FYI, my reader is a plugin class. Is AVSucdReader a plugin class as well? Thanks a lot for the help.

Best,
xunlei

By the way, don't let yourself confuse by the fact that that particular reader currently does only fill "Cell/Point Array Status" for binary AVS UCD files (vtkdata-5.6.1.zip:Data/cellsnd.bin.inp), but not for ASCII AVS UCD files (vtkdata-5.6.1.zip:Data/cellsnd.ascii.inp)
