[vtkusers] problem with vtkFloatArray

[Song Li]

I use:
vtkFloatArray *polyScalars = vtkFloatArray::New();

and the compiler told me:
-----------------------------------------------------------
The indicated type is incomplete.

    vtkFloatArray *polyScalars = vtkFloatArray::New();  //changed to fit
vtk4.0
                                                   ^
-----------------------------------------------------------
what is 'incomplete' here , anybody know what's wrong with this declaration ?
