[vtkusers] Using vtkXMLPolyDataWriter from Java

[Sebastien Jourdain]

The only 2 things that I find strange are:

writer.SetInputConnection(elementFaceActor.GetMapper().GetOutputPort()); //
(option 1)
writer.SetInputData(elementFaceActor.GetMapper().GetInputAsDataSet()); //
(option 2)

Which option are you using? What type of dataset are you using initially?
Did you try vtkDataSetWriter/Reader, to see if you had similar behavior?
