[vtkusers] how to initialize a vtkDataArray

[Song Li]

Hi,
  Just wondering how to create a vtkDataArray, seems the code like :
"vtkDataArray *xyz = vtkDataArray::New();" is not allowed by compiler,
and if I don't do that, compiler will pass it but the program will crash
at "xyz->SetNumberOfTuples(x);" , so is there any way to create it.
  Just want to use vtkDataArray in V4.0 instead of vtkScalars in
V3.2....
  Thanks!
