[vtkusers] file update problems

[Dominik Szczerba]

Hi,
I read a file in an unstructured reader, create a pipeline and render. 
Now I change the reader's filename (SetFileName) to some other filename 
and update. The whole pipeline gets executed/updated properly but the 
color scalars, which are completely disregarded. I tried updating my 
components downstream, but with no luck. What did I forget?
Thanks for any hints,
Dominik
