[Paraview] Ordered xml inputs?

[Sven Buijssen]

David,

I had a short glance at your code and there are two things I find intriging:

1) Your XML mixes the port_index="." and helper method approach for property
SourceDataSet:

      <InputProperty
         name="SourceDataSet"
         port_index="2"
         command="AddSourceConnection"
         clean_command="RemoveAllSources">

You'll have to change the command to "AddInputConnection", in particular because
method AddSourceConnection is merely declared in your *.h file, but there is
nowhere any corresponding code for it. (It's not inherited from class
vtkPolyDataAlgorithm.)

2) Same holds for the clean command: RemoveAllSources() is referenced in the
XML, declared in the header file, but not defined. Whereas RemoveAllInputs() is
inherited from class vtkAlgorithm.

Sven
