[vtkusers] polydata possible bug

[Theodore Papatheodorou]

Hi all,
I have noticed something lately which I think it is a bug. I am creating 
some 4D polydata structures. If I query one of the points it returns the 
correct coordinates. However when I try to save the polydata it treats 
it as a 3D dataset and saves only up to a certain point. So for example:
Instead of saving the data as:
x y z a,  x y z a, x y z a,.....
it saves it as:
x y z, a x y, z a x,....
Anybody encountered this before? Any solutions?
