[Paraview] No scalars menu in gradient filter

[Peter Delmont]

Hello,

In the manual about the 'gradient filter' in the 'Paraview Guide'(page  
187), three different menus are mentioned, which should specify the  
gradient to be calculated.  Namely: the "input" menu, which specifies  
the file, the "Scalars" menu, which specifies the scalar from which  
the gradient has to be calculated, and the "dimensionality" menu,  
which specifies the dimensionality in which the gradient needs to be  
calculated.

When using paraview 2.6, only 2 menus appear on the screen, the  
"scalars" menu is missing.  When applying this filter, the new file is  
exactly the same as the previous file.
When using paraview3.2 for exactly the same problem, the "scalars"  
menu appears on the screen, but when I select it, ParaView crashes  
with the error message: "segmentation fault".

I`m using the .vti AMR HierarchicalBoxDataSet format, with pointing to  
. vti ImageData files.
Anybody has some explanation for this behaviour or hints how to solve  
this problem?

Thanks in advance.
Best regards,
Peter
