[vtkusers] vtkDataSetAttributes problem

Not sure if I follow you. So Theoretically only the active arrays of each
type should return a -1 then?
These are the values I get (Name, Data type and attribute type) of my
arrays. The last entry shows the correct attribute type.
As you see it does identify Array0,Array1 and Array5 correctly. Tough I get
-1 for all the following Scalars and Tensor.

Array0: Materials                    Type: int                    
Attr.Type: 0        (Scalar)
Array1: Strain                        Type: double                Attr.Type:
4        (Tensor)
Array2: vonMisesStrain            Type: double                Attr.Type: -1      
(Scalar)
Array3: Stress                        Type: double                Attr.Type:
-1      (Tensor)
Array4: vonMisesStress            Type: double               Attr.Type: -1      
(Scalar)
Array5: Displacement               Type: double                Attr.Type: 1      
(Vector)
Array6: DisplacementMagnitude Type: double                Attr.Type: -1     
(Scalar)

Hmmm, ok after taking a look upon them now it seems, that it might return
the actual type for the active array(the first scalar,tensor,vector it comes
accross) and -1 for the rest?
In that case what approach would be best to differentiate them. Do I have to
set each of the arrays as the active one first, to be able to read out it's
attribute type or is there a better approach?

I have the feeling I still lack some basic knowledge about
Scalars,Tensors,Vectors in general and missing something simple.
Will try to read up on it in the following days. Any advice and suggestions
on how to handle the differentiating would be welcome.
