[vtkusers] UpdateExtent is not updated

[Erbacher, Markus]

Hello to all,

I am using vtk 4.2.
I had to implement an filter on my own. It seems to work fine, as long
as the input does not change its dimensions. If that happens I get a
warning that the UpdateExtent does not lie within the wholeExtent. I
figured out that the UpdateExtent has not been updated. 

I just reimplemented "ExecuteData". 

Is there any function I missed to implement to achieve this update?
Do you have other advise how to get the UpdateExtent updated?

Thank in advance for your help
