[Paraview] AddArray does not influence the GUI

[Henning]

Hi, 

I try to add an array to PointData of a vtkUnstructuredGrid object:

Source1info = GetActiveSource()
Source1 = servermanager.Fetch(Source1info)

test = vtk.vtkDoubleArray()
test.SetName('test')
test.SetNumberOfTuples(Source1.GetNumberOfPoints())

Source1.GetPointData().AddArray(test)


Unfortunately the newly added array does not show up in the GUI. How can this be achieved?


Thanks
Henning
