[vtkusers] DecimatePro provide holes?

[Markus Erbacher]

Hallo,
 
Why does DecimatePro provide holes in my Object? Or is it normal that
DecimatePro destroys the object
 
These are my parameters:
 
            DecimatePro->PreserveTopologyOff();
            DecimatePro->PreSplitMeshOn();
            DecimatePro->SplittingOn();
            DecimatePro->BoundaryVertexDeletionOn();  
            DecimatePro->SetTargetReduction(0.9);
 
Do you have any ideas?
